  ci: Reduce lint job setup costs
  
  Avoid fetching unnecessary history and submodules for lightweight lint
  jobs. Run changelog validation without Hadrian.
  
  Because the lint-author job is now based on the .lint template directly,
  we enhance it to allow Git to read from the runner-owned checkouts,
  In the previously used .lint-params template, this permissions issue was
  addressed via `chown`.
  
  Closes #27521.
