fix: follow-up fixes for TinyFish browser provider salvage

- Remove ENV_VARS_BY_VERSION[23] entry: adding optional env vars
  does not require a config version bump (deep-merge handles it)
- Replace change-detector test (assert _config_version == 23) with
  invariant test (assert positive int)
- Add TinyFish case to setup.py missing_browser_hint
- Add TINYFISH_BROWSER_TIMEOUT to set_config_value allowed keys
- Add contributor simantak-dabhade to AUTHOR_MAP

hermes_cli/config.py
