Arian van Putten af9a980c7d Lock third-party actions
A caller of this action can lock this action to a specific commit. However because the action itself does not lock its dependent actions to a specific commit this opens the end-user up to possible supply-chain attacks if the dependent actions rewrite their tags.

This PR changes all third party actions to be explicitly locked.

Dependabot will still work and update these hashes for you


I also suggest installing https://github.com/ossf/scorecard in this repo. It will report about these kind of issues.

Note that you should in turn have to audit all the third party deps of the actions that your action depends on. In general this is all a bit of a mess and GitHub's security model is very meh

e.g. see https://github.com/ossf/scorecard/issues/2189
