In order to re-use our browserslist config across babel, autoprefixer
and other tools, we are moving it to a separate file.

Furthermore we update browserslist itself, because why not.

Add PG trigger for has_external_issue_tracker

See merge request gitlab-org/gitlab!51852

We cache whether a project has an External Issue Tracker integration
enabled in the `has_external_issue_tracker` column on `projects`. It
will be `TRUE` if the project has any integration (a record in
`services`) with a category of "issue_tracker" enabled.

This was previously maintained with application code.

This cache is easy to fall out of consistency when we fail to maintain
it during bulk operations (including PostgreSQL cascading deletes
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/48163/) as
mentioned in:

- https://gitlab.com/gitlab-org/gitlab/-/issues/273574#note_457006686
- https://gitlab.com/gitlab-org/gitlab/-/issues/289798

As Ecosystem is increasingly changing integration data using bulk
operations this has been changed to be maintained through a PostgreSQL
trigger.

Add finder class for fetching commits with a certain Git trailer set

See merge request gitlab-org/gitlab!49243

Remove duplicated shared examples

Work around vue/one-component-per-file violations

See merge request gitlab-org/gitlab!51626

Update Workhorse to v8.60.0

See merge request gitlab-org/gitlab!51965

This class fetches all commits in a range in batches, selecting only
commits with a certain trailer set. This class will be used to fetch the
commits that should be used to generate a changelog.

This builds on the changes introduced in
https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2842 and
https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2999. To take
advantage of these changes, we also bump the Gitaly Gem version and add
fallback code for getting trailers using Rugged; as Rugged is still in
use. In addition, we change the merge_request_diff_commits table and the
MergeRequestDiffCommit model to support storing the trailers as JSON.

See https://gitlab.com/gitlab-com/gl-infra/delivery/-/issues/1365 for
more information.

Add improved copy and rename the files

See merge request gitlab-org/gitlab!51757

Fix top border-radius of the login box

See merge request gitlab-org/gitlab!51950

This enables the synchronization of Feature Flags to Jira, using the
endpoints described at:

  https://developer.atlassian.com/cloud/jira/software/rest/api-group-feature-flags/#api-featureflags-0-1-bulk-post

When a user has enabled the GitLab application in their Jira project,
feature flags will be associated with Jira issues if the Jira issue keys
are mentioned in the feature flag description.

Apply GitLab UI button styles to button _blank_state_ee_trial

See merge request gitlab-org/gitlab!51778

Move Danger code from lib/ to tooling/ [RUN ALL RSPEC]

See merge request gitlab-org/gitlab!51566

These were added because of Rails eagerload.
These files are now moved out of Rails eagerload path,
so the conditionals are not necessary.

Test deprecation of `text/plain` on all endpoints

See merge request gitlab-org/gitlab!46133

This reverts commit 3211640a.

Remove custom Danger check for frozen_string_literal comments

See merge request gitlab-org/gitlab!51930

Add metric definitions to Product Intelligence Dangerfile

See merge request gitlab-org/gitlab!52073

Add basic components for packages settings

See merge request gitlab-org/gitlab!51883

- source

- snapshots

Add missing test coverage on Group API spec

See merge request gitlab-org/gitlab!52055

Migrate EE MrWidgetOptions spec to @vue/test-utils

See merge request gitlab-org/gitlab!51926

Fix a Bundler deprecation

See merge request gitlab-org/gitlab!51995

Add auto-fix Label

See merge request gitlab-org/gitlab!50657

We need to assign a special label to identify bot's MRs

This is redundant with Rubocop's Style/FrozenStringLiteralComment cop,
which we didn't have enabled when this was introduced.

To preserve the same behaviour we also:

- Switch to `EnforcedStyle: always_true`, to forbid `false` values.
- Replace the wildcard list with an explicit list of all violations,
  so we still catch all newly added files.
