Alter the formatter-factory-callback for WikibaseRepo.datatypes.php PT:wikibase-property to use the new linking formatter that we just created in T255418
We should keep the PY:wikibase-item formatter the same (not linking)
This will likely require splitting the newItemPropertyIdHtmlLinkFormatter method into 2 methods, one for Items and one for Properties, each injecting the right NonExistingEntityIdHtmlFormatter for the situation (right now that is not injected, but made in the constructor)
