So funny story, true story. I tried to run the test locally, but
didn't make it past setting up Gitaly.

Here's what I tried:

First attempt:

`git clone gitlab-ce`
`cd gitlab-ce && bundle install`
`be rspec`

This didn't work because I was missing the config/database.yml, I
didn't see a `script/bootstrap` so I looked in the readme which
redirected me to a webpage which redirected me to the
gitlab-development-kit.

Second attempt:

`gem install gitlab-development-kit`
cd gitlab-development-kit
gdk init
gdk isntall

This broke somwhere along the way because it couldn't install Gitaly
because my go version was too low. But it did clone the gitlab repo
again and this time it did have a config/database.yml.

So I tried to cd into it and `be rspec
spec/lib/gitlab/database/migration_helpers_spec.rb` which complained
about the database not being configured so I:

- Changed the socket to localhost (in the config/database.yml)
- `createdb <dev_db>` `createdb test_db`
- `be rake db:test:prepare`

Great success, it was doing things! But then failed when it came at
the Gitaly step.

Since I only want to change these three lines, at the point I gave up
and entrusted the pipeline to do its thing.

What I would have liked:

- A 'It's a Rails system, I know this' readme/docs (It's in there
  somewhere just couldn't find it)
- A way to run tests without having to use Gitaly
- Not having too install all the things for a small fix (I get why'd
  you want this, but to me it's overkill)

It's fine to upgrade from 11.11.x to 12.x, so we remove the requirement
to first upgrade to 12.0.x.

Will apply identation from
CSS to collapsible sections

Merge branch '63399-intermittent-spec-failure-in-spec-models-ci-pipeline_schedule_spec-rb-131' into 'master'

Refactor file locking docs

See merge request gitlab-org/gitlab-ce!29686

- Remove outdated 'introduced in' section
- Update/remove images

The rather cryptic:

      "fk_#{Digest::SHA256.hexdigest("#{table}_#{column}_fk").first(10)}"

Was too much for emacs too handle*, since it was coming from the Rails
codebase I took their way of doing the same thing and applied it here.

I think it's easier to read and it also makes emacs render the
migration helpers pretty again.

* not true, emacs can handle anything, leave emacs alone!

Fixes flaky master

Two static memory benchmarks will be included in our CI pipeline. It
will load gems from the Gemfile and check the amount of RAM consumed
as well as the number of objects allocated and retained.
Aggregated values will be included as 'metrics' into MRs while full
reports will be downloadable as job artifacts.
