Currently, only group owners can reset group runner registration tokens. However, project maintainers are able to reset project runner registration tokens. Given Permission alignment for OWNER and MAINTAINER r... (#374607), we're aligning the permissions between group owners and project owners.

Proposal

Make :update_runners_registration_token permission only available to project owners.

Implementation plan

1. Move enable :update_runners_registration_token to rule { can?(:owner_access) }.policy do block.
2. Adapt specs.
