Issue #3633219: Add test coverage for plugin descriptions.

Fons Vandammerequested to merge
issue/metatag-3633219:3633219-test-coverage into 2.2.x

Adds test coverage so plugin descriptions can't silently disappear again, see #3633005.

  • New kernel test MetatagPluginDescriptionTest: every tag and group plugin must have a description in its definition, and description() must return it. Fails on 2.2.1, passes with the fix from #3633005.
  • MetatagAdminTest::testDefaults now checks that the Title description is shown on the global defaults form.

This code was mainly generated by an AI with my guidance, I reviewed, tested, and refined it.

Closes #3633219
