Disable rugged auto-detect when Puma threads>1

See merge request gitlab-org/gitlab!22328

If Puma is in use and Puma threads is more than 1, it is expected to
have performance lose by using Rugged patches, because of Rugged calls
does not release Ruby GVL while doing IO. So in this case, we will
ignore rugged automatic detect `can_use_disk?`.

Improve GitLab pages docs

Refactor `readmeFile`

Closes #121727

See merge request gitlab-org/gitlab!22243

These both ended in .yaml, not .yml, and so weren't picked up by the
changelog generator.

https://gitlab.com/gitlab-org/gitlab/merge_requests/18126

This job checks that files in the unreleased changelogs directories have
the correct .yml extension. It ignores the .gitkeep files already there.

As yamllint errors when a path doesn't exist, we have to make sure to
only add ee/changelogs when ee/ exists. (i.e. we're not adding this
check in the FOSS version.)

Merge branch '36017-move-analytics-out-of-more-in-top-navbar-and-merge-with-instance-statistics' into 'master'

Ensure that instance statistics links are only displayed if a user has access to the features

See merge request gitlab-org/gitlab!22476

By asserting that the epic title is the same of the issue that
was promoted we are already testing that issue promotion works, so
better to remove this extra assertions that might cause test flaki-
ness since sometimes automatic discussions take longer to render.

Also, by removing an extra step + assertion, we make the test a bit
faster.

Finally, this way the code gets a bit shorter.

In getFileData, getRawFileData actions, and SET_FILE_RAW_DATA mutation,
ignore the early returns for when a file is deleted and readded. This
fixes issues with incorrect diff appearing because raw data wasn't
loaded correctly for deleted and readded files.

Quarantine performance bar spec

Perform a real search and wait longer for success in elasticsearch QA tests

See merge request gitlab-org/gitlab!21984

It can take longer than expected for elasticsearch to be ready to index
new data. This makes sure it actually does return valid results, rather
than only accepting a query.

Remove unnecessary assertions from epic management end-to-end test

Closes #121573

See merge request gitlab-org/gitlab!22612

Instance statistics links should only be displayed when the features are
available for a user.

We need to seperate the logic for instance statistics and analytics.
