We replace the usage of WikiPage::CreateService with the wiki_page factory in the specs.

Replaces all the explicit include metadata syntax in the specs (tag:
true) into the implicit one (:tag).
Added a cop to prevent future errors and handle autocorrection.

The helper creates a fork of a project with all provided attributes,
but skipping the creation of the repository on disk.

Closes #38808

Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/38389

Previously the fork button was disabled for all users if they have
exceeded their project limit. This fixes that by changing the check
to see if the user can fork to a group instead of their own namespace.

This behaviour is already possible by visiting the new fork page
directly, so this just fixes the button being disabled.

Closes #38462

Closes gitaly#562

This fixes the breadcrumb titles not having links. This was a regression
in the updated breadcrumbs introduced in 10.0.

This introduces the link for all pages rather than selectively doing it.
This will cover issues, merge requests, pipelines, jobs etc.

Closes #38059

This was caused by the `notes` global class not existing when the
`file_comment_button` code is run. The notes class was used to check
if the diff is currently in parallel view or not. To get around this
I've added a check into the `file_comment_button` JS to check if the
view is currently parallel or not.
