Fixes Admin Runners table not wrapping the content

Closes #51549

See merge request gitlab-org/gitlab-ce!21802

`delete_all` doesn't support limit, so you'd need to subquery
that. And instead of subquerying with `where(id: query)`, it's better
to use an `INNER JOIN`. This method also works with MySQL, while
subquerying doesn't (without another layer of subquerying)

Fix link to blog posts in docs

See merge request gitlab-org/gitlab-ce!21820

The 9.4 to 9.5 and 9.5 to 10.0 guides missed a closing backtick. This
was corrected in the 10.0 to 10.1 guide, from which subsequent guides
were written without the error.

Due to a missing `s`, a link to the blog archive
for releases was broken.

Delete container repository tags outside of transaction

Closes #51380

See merge request gitlab-org/gitlab-ce!21679

This is because the CNG pipeline now relies on the assets
compiled here in the gitlab:assets:compile job (It waits
up to 30 minutes for them)

Without this change, the cloud native job was holding up
the pipeline, preventing the assets compile job from being
run.
