Changes proposed in this Pull Request:

In order to help protect against compromised actions, instead of including actions based on their major version (like v4), this PR switches all the actions we use to pull based on the commit hash from the latest release.

While this does impact maintenance a bit going forward, it ensures that we we're always using actions that we (hopefully) trust and if an action gets compromised (which happens) we don't have to worry that we're using a compromised action. This also goes along with what GitHub suggests.

Steps to test the changes in this Pull Request:

Ensure all our workflows still run as expected

Not sure what this workflow was used for in the past but doesn't actually contain a valid workflow so it throws an error anytime code is pushed, so figured we might as well delete it
