dependency aws-encryption-sdk v3.1.0 uses incompatible downstream dependency (cryptography >=40)

aws-encryption-sdk v3.1.0 (python hook runtime dependency) has a dependency on cryptogrpahy>2.5 (see https://github.com/aws/aws-encryption-sdk-python/blob/7950abd73ee333407d2dadd02ef2d57c3df464cf/requirements.txt#L2). This causes python hooks to be bundled with the latest version of cryptography (40.0.1), however the cryptography package has recently fully deprecated a method used by aws-encryption-sdk v3.1.0 (`utils.verify_instance`). This is resulting in a runtime exception for python hooks bundled with cloudformation-cli-python-lib v2.1.15:
```
Unable to import module 'x.handlers': cannot import name 'verify_interface' from 'cryptography.utils' (/var/task/cryptography/utils.py)
```

aws-encryption-sdk v3.1.1 no longer uses the `verify_instance`method and looks like it could be a suitable replacement (see: https://github.com/aws/aws-encryption-sdk-python/releases/tag/v3.1.1).
