Previously, the file size check required a complete graph walk,
which was slow.
This change optimizes the process by using an existing method
that checks only the quarantine directory, improving performance.

Additionally, since this is an EE feature,
a new EE-specific FileSizeCheck class was introduced
to retrieve and apply the push rule file size limit

Changelog: changed
EE: true

Releases a new experience on `Your work` -> `Projects`.
Default tab is now `Contributed`, improved layout,
add Delete and Edit actions.

Changelog: changed

Remove unnecessary inherits

Remove .gitlab-qa-install extends

Remove qa-base reference

Update notify-slack job

Update the way variables are triggered

Set ruby version in pipeline creator

Extract omnibus e2e test base job

Extract common e2e test variables

Inherit omnibus cache related variables

Move definition to omnibus

Skip clone for release-set job

Use OS variables for omnibus qa job images

This both increases speed but also reduces flakiness

Also makes both legacy and work item versions visually identical.

When the feature flag `ci_release_cli_catalog_publish_option` is
enabled, the backend requires the `legacy_catalog_publish` parameter.

Removing redundant code now that pipeline variables code is successfully abstracted

Changelog: removed

Use an API function to reduce time and flakiness

ProjectPush is a slower way of creating a file.
Use Commit instead

This adds a runner to the Enable Scanning
spec, which looks to reduce flakiness caused
when the test can't merge the merge request
due to waiting on a pipeline
