Whenever "Enable image uploads" is enabled for a text editor, the editor_file_reference filter should be enabled

Like I wrote 2 years ago in #12: this issue is now effectively obsolete.

Thanks to this:

ckeditor5_imageUpload:
  ckeditor5:
…
  drupal:
…
    conditions:
      imageUploadStatus: true
      plugins: [ckeditor5_image]

However, this only solved it for ckeditor5 text editor plugins.

Thanks to ✨ [PP-1] Mark parts of CKEditor 5 and Editor config schema as fully validatable Postponed , we can now actually enforce this for all text editor plugins! We could do something like:

diff --git a/core/modules/editor/config/schema/editor.schema.yml b/core/modules/editor/config/schema/editor.schema.yml
index 0c0278b715..22817c666c 100644

Similar to what \Drupal\ckeditor5\Plugin\Validation\Constraint\CKEditor5MediaAndFilterSettingsInSyncConstraintValidator does!
