Updating github actions versions

I don't know much about github actions, but when updating my node in the registry i noticed a warning in the action regarding an update in the nodejs version used by github actions by June.

The current checkout and setup-python actions referenced by your action point to old versions that may not work with the new nodejs version.

I guess you need to bump both of them to v6 ?

Locate the workflow references to the checkout and setup-python actions mentioned in the issue, then check their current versions and the GitHub Actions Node.js warning. Update both references to the required versions, such as v6 if confirmed, and verify that the warning is resolved.
