cloud-platform-environments github version commit hash replacement #6693

[jackstockley89]

Background

GitHub security good practices documentation says you should use the commit hash instead of the version

`Pin actions to a full-length commit SHA

Pinning an action to a full-length commit SHA is currently the only way to use an action as an immutable release. Pinning to a particular SHA helps mitigate the risk of a bad actor adding a backdoor to the action's repository, as they would need to generate a SHA-1 collision for a valid Git object payload. When selecting a SHA, you should verify it is from the action's repository and not a repository fork.`

Approach

Review all actions and replace all versions with commit hashes as this is best practice and covers Cloud Platform for the future
