CI updates and matrix of Elixir/Erlang versions (#29)

This change updates the CI so:
- We test different Elixir/Erlang versions
- We test that there are no unused versions in the mix.lock
- Credo version is updated
- Development versions are updated
- Update actions version to avoid deprecations
- Do not run CI on guides changes
