Partially work around pending deprecation of pkg_resources (#12368)

* Handle deprecation of pkg_resources

* Replace `pkg_resources` with `importlib_metadata` for `spacy info
--url`
* Remove requirements check from `spacy project` given the lack of
alternatives

* Fix installed model URL method and CI test

* Fix types/handling, simplify catch-all return

* Move imports instead of disabling requirements check

* Format

* Reenable test with ignored deprecation warning

* Fix except

* Fix return
