Added keyboard shortcut to navigate to issue boards

## What does this MR do?

Adds a keyboard shortcut of `g l` to navigate to issue boards.

`g b` would work nicer. However that is taken by builds. Open to suggestions.

## What are the relevant issue numbers?

Closes #21218

See merge request !6248

Update snippets UI

## What does this MR do?

Updates snippets UI _(mainly mobile view)_ to new UI proposed in #18849.

## Are there points in the code the reviewer needs to double check?

Does anyone know the implementation difference between `app/views/snippets/show.html.haml` and `app/views/projects/snippets/show.html.haml`? I have only been updating the latter as it's the only one I can find implemented. I assume the former is rendered somewhere seeing as there is controllers for it too. But this doesn't seem very DRY from my current perspective.

Restore gl_dropdown.js changes

Restores `fieldName` to allow only string values. `fieldName` was changed to accept  function as a value in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/581 Since the approach changed in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/687 there's no need to accept function as value.

Improve validity of spec/features/todos/todos_filtering_spec.rb

Previously, we were checking that a CSS selector string didn't have some
page-related content, which, of course it didn't.

Now we check against the actual content of the selector, we use a more
semantic selector, and we add an additional expectation for the text
that _should_ be there, as an additional sanity check.

* `name 0:1 ruby` => `name ruby`

Trigger autosize update after template selection

## What does this MR do?

Triggers an autosize update after selecting an issue template.

The autosize plugin doesn't react to value changes and therefore doesn't automatically update when the user selects the template. This merge request adds it so that it detects if the editor the template selector is a jQuery object (not Ace editor) & then triggers the autosize event to allow the user to scroll the textarea.

doc/ci/quick_start/README: improve sentence about link to a Lint tool

## What does this MR do?

It improves the `doc/ci/quick_start/README.md` documentation.

## Are there points in the code the reviewer needs to double check?

The reviewer can check that there is no more **CI settings** menu and that the Lint tool can be accessed under **Pipelines > Pipelines** and **Pipelines > Builds**.

## Why was this MR needed?

Because the CI quick start documentation was not correct.

## Screenshots (if relevant)

## Does this MR meet the acceptance criteria?

It is not a code change so I don't think the below criteria are relevant.

doc/user/permissions: update option and menu names

## What does this MR do?

This fixes `doc/user/permissions.md` documentation.

## Are there points in the code the reviewer needs to double check?

The reviewer can check that the name of the option is now **Public pipelines** and that this option is in **Project Settings > CI/CD Pipelines**.

## Why was this MR needed?

Because the previous name of the option and of the menu had not been updated in `doc/user/permissions.md` when they were changed.

## Screenshots (if relevant)

## Does this MR meet the acceptance criteria?

This is a documentation only MR, so I don't think it needs to pass all these acceptance criteria.

Fix the ordering of transition callbacks

Because pipeline status could be changed for the builds in the next
stages, if we process next stages first, the current build would be
out of synchronized, and would need a reload for that matter.

Alternatively, like what I did in this commit, we could process the
next stages later (by using `after_transition` rather than
`around_transition`), and complete what're doing for the current
build first. This way we don't have to reload because nothing is
out synchronized.

Note that since giving `false` in `after_transition` would halt the
callbacks chain, according to:

https://github.com/state-machines/state_machines-activemodel/blob/v0.4.0/lib/state_machines/integrations/active_model.rb#L426-L429

We'll need to make sure we're not returning false because we don't
intend to interrupt the chain.

This fixes #22010.

After this fix, both pipeline events and build events would only show
up once.

This MR fixes the migration that removes the unique index/constraint from `merge_request_diffs.merge_request_id`

See merge request !6346

For whatever reason on some PostgreSQL installations there would be a
separate UNIQUE constraint on the merge_request_id column. Rails'
index_exists?() returns false for this constraint (even when using the
full name), yet the indexes() method returns it.

This commit changes the migration so that the constraint is dropped as
well. MySQL installations don't appear to be affected.

Fixes gitlab-org/gitlab-ce#22136

10.6.4/10.6.5/10.6.6 contains some changes regarding marking blobs as binary, this can improve page loading times.
