Update documentation for monthly maintenance tasks

We need to revisit how we handle the maintenance tasks on this list: https://gitlab.com/gitlab-org/technical-writing/team-tasks/-/blob/main/.gitlab/issue_templates/tw-monthly-tasks.md?ref_type=heads

Which are still needed, and how should they work?

Current chores:

Keep:

  • Look for uncompressed images. (No change needed)
  • Search for and remove expired redirect files. (In progress via #156 (closed))
  • Search for and report on pages not in the global nav. (done, see make check-pages-not-in-nav)
  • Search for <!--- start_remove and delete any content with dates in the past. (in progress via !459 (merged))
  • Check for unlinked images. (done, see !428 (merged))
  • Check for broken external links. (done, see !421 (merged))
  • Check for trailing whitespace. (done, see !447 (merged))

Drop 🎉 :

  • Review the Kramdown build logs for warnings.
