[Meta] Tasks to deprecate Forum

Update to latest template from the policy → .

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

There are references to forum in the following

• core/tests/Drupal/KernelTests/Config/Schema/MappingTest.php:
• core/modules/system/tests/src/Functional/Update/Y2038TimestampUpdateTest.php:
• core/modules/node/tests/src/Functional/NodeTypeTest.php:

This could be an issue for comments;

$ grep --exclude-dir={vendor,node_modules,forum,themes} -riw 'forum' core | grep -v phpstan-baseline.neon | grep -v Test | grep -vi migrat | grep -vi "drupal[6|7].php" 
core/lib/Drupal/Core/Extension/InfoParserInterface.php:   * See forum.info.yml for an example of a module .info.yml file.
core/lib/Drupal/Core/Entity/entity.api.php: * - The Forum module defines a content type in node.type.forum.yml and a
core/lib/Drupal/Core/Config/Entity/ConfigDependencyManager.php: * dependencies key. For example, the Forum module provides the forum node type
core/lib/Drupal/Core/Config/Entity/ConfigDependencyManager.php: * and in order for it to be deleted when the forum module is uninstalled it has
core/lib/Drupal/Core/Config/Entity/ConfigDependencyManager.php: * an enforced dependency on the module. The dependency on the Forum module can
core/lib/Drupal/Core/Config/Entity/ConfigDependencyManager.php: * type configuration entity that depends on functionality provided by the Forum
core/lib/Drupal/Core/Logger/RfcLoggerTrait.php: * @see https://groups.google.com/forum/#!topic/php-fig/Rc5YDhNdGz4
core/lib/Drupal/Core/Render/theme.api.php: *     when the forum is rendered, following render array can be used:
core/lib/Drupal/Core/Render/theme.api.php: *       '#theme' => array('forum__' . $tid, 'forum'),
core/lib/Drupal/Core/Render/theme.api.php: *       '#forum' => $forum,
core/lib/Drupal/Core/Render/theme.api.php:  // Kill the next/previous forum topic navigation links.
core/modules/comment/comment.module: * Users can post comments to discuss a forum topic, story, collaborative
core/modules/system/tests/modules/url_alter_test/url_alter_test.install:  // Set the weight of this module to one higher than forum.module.
core/modules/path/path.module:      $element['value']['#description'] = t('Specify the existing path you wish to alias. For example: /node/28, /forum/1, /taxonomy/term/1.');
core/modules/field/src/Entity/FieldStorageConfig.php:   * classic use case for this is node body field storage since Book, Forum, the
core/MAINTAINERS.txt:Forum

And there are plenty of references in themes.
grep --exclude-dir={vendor,node_modules,forum} -riw 'forum' core | grep -v phpstan-baseline.neon | grep -v Test | grep themes | grep -vi migrat | grep -vi "drupal[6|7].php"

Removing 📌 [11.x] Remove forum CSS from themes and profiles Closed: duplicate from the Issue Summary. That will be done when Forum is removed.

Thanks to everyone who worked on the child issues to make this happen!

I am adding credit to myself for the overall admin required to keep this on track.
