Actions Updates - yaml & json validation

[GrantBirki]

Actions Updates

This pull request does the following:

• Updates actions/setup-go and actions/setup-python to v4 tags
• Adds a new Actions workflow to validate json and yaml files in the repository

Why?

I recently developed a new GitHub Action to validate json and yaml files. It runs in under 5 seconds for this repository and it is a native JS Action. I noticed that @Raffo (who I work with at @github) contributes to this repository in my feed so I took a look at this repo. I saw there were a handful of *.yaml files in this repo and figured it would be helpful if they got validated on pull requests through GitHub actions so maintainers can know if they are valid or not before merging. Hopefully this helps! ❤️

While I was making commits, I also upgraded some Actions tag versions as well

Checklist

• Unit tests updated
