Don't commit artifact in sender

[wk9874]

Fix 'cannot commit artifact' error message in sender

Python Version(s) Tested: 3.10

Operating System(s): Ubuntu

📝 Summary

Sender automatically does .commit on any objects read from the cache. This isnt required for artifacts, hence you get this error:

INFO:simvue.FileArtifact:Cannot call method 'commit' on write-once type 'Artifact'

🔄 Changes

Simply add a check into the sender so that commit isnt called if the object class is a subclass of ArtifactBase

✔️ Checklist

• Unit and integration tests passing.
• Pre-commit hooks passing.
• Quality checks passing.
