gpt4-o for browser-use

[MagMueller]

Thank you very much for adding browser-use, it works great!

Currently supported models:
'browser:gpt-4-turbo', 'browser:gpt-4', 'browser:gpt-3.5-turbo'

It would be great to use also 4o and other more advanced and cheaper models.

I would also suggest in the README.md to use gpt-4o by default.
