Also updates CI pypy versions to be 3.9 and 3.10 which are the currently [supported versions](https://www.pypy.org/posts/2024/01/pypy-v7315-release.html). Otherwise latest cryptography doesn't ship with pypy3.8 wheels and is unable to build on windows. Also updates the `codecov-action` to v4 which fixed some intermittent uploading errors.
