See merge request !4464

Rename Ci::Commit in specs

This is second iteration of renaming Ci::Commit occurences, this time I try to rename all `let's` and `factories` to match what type of object is created:

1. Rename factories: `ci_[...]_commit_[...]` to `ci_[...]_pipeline_[...]`,
2. Rename all `let's(:[ci_]commit)` to `let(:pipeline)`,
3. Rename all occurrences of `[ci_]commit` to `pipeline` if Pipeline object is created

License finder gem

Every time a gem is added to the Gemfile, or a gem is updated with a new dependency or change of license, LicenseFinder will check to ensure that the license in use has been whitelisted for use in the project. GPLv2 and GPLv3 libraries are not allowed to be linked-to from non-GPL projects (e.g. the MIT-licensed GitLab CE or proprietary EE), otherwise we're violating the license.

Use better_errors editor links in sherlock

Closes #18254. Uses the same editor configuration of `better_errors`
so that you don't have to configure things twice. Remember to have a
custom initializer that specifies your editor.

Example for atom. File `config/initializers/better_errors.rb`:
````ruby
if defined?(BetterErrors)
  BetterErrors.editor = "atm://open?url=file://%{file}&line=%{line}"
end
````

See merge request !4497

Remember to configure your `better_errors` editor to point to your program of preference

Make sure to mention the GNU Project and OSI-provided information regarding the GPL so no one tries to disagree with that decision.

Add gems and licenses that were previously missing. Approve a number of licenses after a bunch of research today.

Also add License Finder to CI (only runs on master).

In order to rehost all our gems in our own gem host, we need to have the legal rights to do so for every gem should they be taken down from RubyGems. License Finder automates checking of gems to ensure that we're in the clear legally.

Approved the MIT License because it essentially allows us to do "whatever" with those gems.

I am not a lawyer.

Fixed issue with activity links not being consistent

Previously, links for opening an issue/merge request & commenting where different. Opening would only have a link on the number whereas commenting would have link on the text as well. This standardises it to include the type as well (ie. issue)

## What are the relevant issue numbers?

Closes #17621

Remove prev/next buttons on issues and merge requests sidebar
