update pinned dependencies (#10278)

this fixes the security alerts those with access can see at
https://github.com/certbot/certbot/security/dependabot

i based what needed to be done to drop python < 3.9.2 support on
https://github.com/certbot/certbot/pull/10077 and concluded we only
really needed to update `python_requires`. we could do a deprecation
period for this, but i think it's not necessary. cryptography didn't
(it's not even in mentioned in [their
changelog](https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst))
and none of the major LTS distros use python 3.9.0 or 3.9.1
