Using commit hashes rather than static versions in GHA

[jsphwhereby]

Description

Summary:

Following the incident regarding tj-actions we have decided to use commit hashes rather than static versions in our GHAs.

Related Issue:

Testing

No changes, the version is the same as the commit hash, this just prevents versions from being overridden with malicious code.
