This needs to be separate from RepositoryPathConverter with the updated regex for

to redirecting to the repository web route.

For example:

/v2/devtable/testrepo/nested/manifests/somedigest" would previously have (correctly) returned

a 404, due to the path not matching any routes. With the regex supporting nested path for extended

repo names, Werkzeug would now (incorrectly) match to redirect to the web page of a repository with

the above path. See endpoints.web.redirect_to_repository.
