Air compatibility

[maelle]

Provide an Air config file skipping all files? https://posit-dev.github.io/air/configuration.html#configuration-skip

[maelle]

To prevent PRs from external contributors messing up with the style, like my PR #275 😅

I set this in my air.toml and it is avoiding these headaches!

[format]
exclude = ["*"]

@ateucher awesome! Could you please PR such a file to this repo? 🙏
