This commit allows the `forgejo-cli actions register` command to change an existing runner's secret, as discussed in #4610. It refactors `RegisterRunner` to extract the code that hashes the token, moving this code to a method called `UpdateSecret` on `ActionRunner`. A test for the method has been added. The `RegisterRunner` function is updated so that: - it relies on `ActionRunner.UpdateSecret` when creating new runners, - it checks whether an existing runner's secret still matches the one passed on the command line, - it updates the runner's secret if it wasn't created and it no longer matches. A test has been added for the new behaviour.
