Description of the Change

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.

How to test the Change
