meta: Add AR codeowners (#4549)

Rationale:
- Dirk is a root codeowner already and so can cover scripts/
- The Transfer Verifier and Notary code is maintained by AR
- The msg_verifier code in the watcher relates to Transfer Verifier
- The pendingmessage code is related to the Notary
- Joel no longer has write access according to GitHub
