workflows: clone without auth (public repo, no basic-auth needed)

Both 'forgejo-runner:$TOKEN' and 'x-access-token:$TOKEN' formulas
are rejected by Gitea's act_runner with HTTP 401:
  remote: Failed to authenticate user
  fatal: Authentication failed

For public repos the simplest fix is: don't send credentials at all.
Plain https://host/owner/repo.git clones unauthenticated and Gitea
serves it (root/drover-go is public).

If/when we move to private repos this'll need a different approach
(GITEA_TOKEN env, oauth2 username, or .netrc) — but that's a future
problem.
