[Meta] Tasks to deprecate Forum [#3267261]

Problem/Motivation

This issue is to coordinate and track the steps needed to move Forum to contrib. See Remove a core module and move it to a contributed project of the deprecation policy.

The contrib project is Forum

The removal of Forum was approved in #1898812: [policy] Deprecate forum module for removal in Drupal 11

Proposed resolution

Remaining tasks

Begin finding someone to maintain the contrib version of the extension.
Move integrations implemented by other modules to the extension.
Create child issues or child meta issues, as needed, to address the following points. Not all points will apply to all extensions.
- Move non-migration tests to the extension.
  - #3264195: Move non-migration tests to Forum in preparation for deprecation
  - #1867642: Expose forum tables to views
- Move Help Topics to the extension.#3336587: Move help topics to forum module
- Remove the extension from one or more profiles.
- Removing references to the extension from database dumps.
- Update Update path tests. See Writing Automated Update Tests for Drupal 8 (or later) for details.
- For a module, handle migrations, if the module has migrations.
- Migration yml and processes that are outside the module but support the upgrade path for that module stay in core. #3336786: [Meta] Handle forum migrations not in the forum module for deprecating forum
- Move migration tests to the module. #3336578: Move migration tests to the Forum module
- Remove forum from block migrations #3371219: Remove forum from block migration tests

Do a thorough search of core for any remaining references to the extension. If references are found, outside of the extension, then create issues to remove the references.

Create the contrib project with a stable release.

Because forum is in a quite a few migration I made an issue to check them separately.

Version:

10.1.x-dev

» 11.x-dev

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch, which currently accepts only minor-version allowed changes. For more information, see the Drupal core minor version schedule and the Allowed changes during the Drupal core release cycle.

There are references to forum in the following

core/modules/system/tests/src/Functional/Update/Y2038TimestampUpdateTest.php:
core/modules/node/tests/src/Functional/NodeTypeTest.php:

This could be an issue for comments;

core/lib/Drupal/Core/Config/Entity/ConfigDependencyManager.php: * and in order for it to be deleted when the forum module is uninstalled it has

And there are plenty of references in themes.
