In 8278b763 the default behaviour of annotation
has changes, which was causing a lot of noise in diffs. We decided in #17382
that it is better to get rid of the whole annotate gem, and instead let people
look at schema.rb for the columns in a table.

Fixes: #17382

This changes Project#protected_branch? to use a query to check if a
branch is protected, instead of loading all ProtectedBranch records into
memory just to check if the list of names includes a given branch name.

This is a combination of 3 commits.

- Update the bare repositories info/attributes if the default branch is updated
- Check the diff attributes of a file before showing a diff
- Update CHANGELOG

- Parameter validation as ISO8601 format

This status will be returned only when there are no failed jobs
that are not allowed to fail.

"CHANGELOG", "NEWS", "HISTORY", and "CHANGES" are recognized as Changelog files.

Also adds relevant tests for each of these names.

Resolves #14864.
