CLI should not raise error on local action paths, when asked to ignore local actions

[jessehouwing]

The gh-actions-lock should probably not error out when I explicitly ask it not to migrate local actions

Plus the message "which are not supported" is incorrect.

gh actions-lock --rescan --no-migrate-local-actions
  ! LOCAL-ACTION .github\workflows\release-test-github-actions.yml
    workflow uses local path actions which are not supported; remove local path actions to continue using the lockfile
✗ 1 of 13 workflows failed: 1 local-action


  Resolution record: C:\Users\JesseHouwing\AppData\Local\gh-actions-lock\logs\run-20260818-193150.723.json

OR execution should fail... But right now a mix of ./ and pinned actions just works.
