feat: add auto-fix-git-user and auto-fix-git-email inputs

Add configurable git identity for auto-fix commits to address 2bndy5's
concern about commit author reflecting the token owner.

- auto-fix-git-user: custom git username for the auto-fix commit
  (defaults to GITHUB_ACTOR)
- auto-fix-git-email: custom git email for the auto-fix commit
  (defaults to GITHUB_ACTOR_ID+GITHUB_ACTOR@users.noreply.github.com)
- When empty, falls back to GITHUB_ACTOR/GITHUB_ACTOR_ID based values
