fix(iast): add google.auth to the IAST denylist [backport 2.15] (#11243)

Backport e33e235 from #11240 to 2.15.

This fix resolves an issue where importing the
``google.cloud.storage.batch`` module would fail raising an
AttributeError

```
  File "site-packages/google/auth/crypt/rsa.py", line 22, in <module>
    RSASigner = _cryptography_rsa.RSASigner
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'google.auth.crypt._cryptography_rsa' has no attribute 'RSASigner'
```
