Admin: Render foreign key models as links for readonly users

[Julien Rebetez]

In the admin UI, when viewing a model for which you have view only permission, foreign key / m2m fields are rendered as plaintext representation of the target object.

It would be nicer to render those as links instead so that a readonly user can navigate through the relationships.

The link should only be rendered if the user has permission to view the target model.

Hi Julian. Thanks for this. I agree, it does sound like a nice enhancement.

Please open a PR from your branch. Commit message/title Fixed #31181 -- Added links....
If you could post a small screenshot of two, showing the improvement, that makes it easier at first glance too.
