refactor: update cookie browsers var and LMArenaBeta availability logic

- In `g4f/Provider/needs_auth/LMArenaBeta.py`, import `has_nodriver` from `...requests` in the same line as other imports
- Change `working` attribute to be set based on `has_nodriver` instead of `True`
- Add new class attribute `active_by_default = True` to `LMArenaBeta`
- In `g4f/cli/__init__.py`, change `--cookie-browsers` argument choices to use `g4f.cookies.BROWSERS` instead of `g4f.cookies.browsers`
- In `g4f/cli/__init__.py`, update `run_api_args` to assign to `g4f.cookies.BROWSERS` instead of `g4f.cookies.browsers`
- In `g4f/gui/gui_parser.py`, change import from `browsers` to `BROWSERS`
- In `g4f/gui/gui_parser.py`, update `--cookie-browsers` argument choices to use `BROWSERS` instead of `browsers`
- In `g4f/gui/run.py`, update `run_gui_args` to assign to `g4f.cookies.BROWSERS` instead of `g4f.cookies.browsers
