Deletion of CKEditor 5 Full-screen Mode (legacy)

The ckeditor5_premium_features_fullscreen module doesn't have a direct dependency on the ckeditor5_premium_features module and can be installed separately. However, during the uninstall process, it tries to call a ckeditor5_premium_features_remove_ckeditor_plugins function which doesn't exist if the ckeditor5_premium_features module is not installed. This leads to an inability to remove the module.

function ckeditor5_premium_features_fullscreen_uninstall($is_syncing) {
  ckeditor5_premium_features_remove_ckeditor_plugins(['fullScreen']);
}

The workaround is to install ckeditor5_premium_features and remove the deprecated module.

This issue can be fixed by copying the ckeditor5_premium_features_remove_ckeditor_plugins function code into the ckeditor5_premium_features_fullscreen_uninstall hook, or by adding a direct dependency on the ckeditor5_premium_features module and providing an update hook to install the main module.
