`ModuleNotFoundError: No module named 'rsa'`

After updating my packages, specifically from google-auth==2.48.0 to google-auth==2.49.1, I'm experiencing the following issue:

Traceback (most recent call last):
  [...]

    from google.appengine.ext.testbed import Testbed

    import rsa
ModuleNotFoundError: No module named 'rsa'

The rsa dependency has been removed in google-auth==2.49.1 (googleapis/google-cloud-python@e8927b9), but appengine-python-standard uses the rsa module without it being a direct dependency. With older versions of google-auth, it worked because of the transitive dependency.
