Deprecate the Ban module

Tests failed as ban module is used in tests. Will work on these tests as part of https://www.drupal.org/project/drupal/issues/3488838 📌 Use a test module instead of Ban in dependency tests Active .

@annmarysruthy, thanks for working to deprecate Ban. I have only glanced at the MR but it looks correct.

Instead of updating the list of remaining tasks in the a comment on the MR can you put in the Issue Summary instead. The issue summary is the first place that contributors go to in order to understand what needs to be done. And reviewers and committers like it up to date so they know what to is expected.

This issue is to be committed last in the task listed in the parent issue so I setting to 'Postponed' and I have updated the remaining tasks accordingly.

Updated remaining tasks.
