Support for the "Manage permissions" tab coming in Drupal 9.4.0 for bundles

Returning back to this, based on what was committed in #2934995: Add a "Manage permissions" tab for each bundle that has associated permissions → it looks like a single line needs to be added to the notation, something like:

* "permission-form" = "/admin/structure/storage/storage_types/{storage_type}//permissions",

Happy to work on this.

I added the specified notations, and now the tab appears but the form is empty, as described in the issue. Not sure if the permissions are expected to have a certain structure in order to be picked up by the form. Will investigate this further, but marking this issue as Needs Work for now.
