Docs required issues process

According to the Release process, 3 weeks prior to release we need to check docs_required-labelled issues and write new documentation, removing the label and commenting in the issue when the work is done.

Ideally, at the time of release, the number of docs_required-labelled issues for the versions being released should be zero.

Comments templates

Removing the docs_required label as this improvement is now documented: https://docs.moodle.org/en/Groups

If you notice that the documentation can be improved, please feel free to log in to the wiki and edit the page. Help in keeping Moodle documentation accurate and up-to-date is much appreciated.
