Hi, I'm newly migrating to ruff and it works so far so good for me, thank you for making this great tool!

However, I noticed that ruff uses the config_dir in dirs crates, which goes to $HOME/Library/Application Support under macOS. Generally I believe that as a CLI tool (and like many others), ruff should probably stick with XDG config home under macOS. When I look into my $HOME/Library/Application Support, they're almost all GUI application stuffs. Also, I think it is expected & intuitional to read config from $XDG_CONFIG_HOME since macOS mostly behave in *nix way.

Please let me know what you think :)
