New versions of GitHub Actions used by bandit

Hello everyone, and thanks for this great tool for Python coders.

I noticed that the following GitHub Actions have been upgraded to version 3 recently:
https://github.com/actions/checkout
https://github.com/actions/setup-python

I think it should be considered to use actions/checkout@v3 and actions/setup-python@v3 everywhere in this project's Actions workflows and check if everything works alright.

Sounds good, did you want to create a pull request on it? I can create an issue from this discussion.
