I believe this might be a duplicate of #4613

I think the issue is that the [Configurations.md](https://github.com/rust-lang/rustfmt/blob/master/Configurations.md#configuration-file-resolution) is pointing to [dirs v1.0.4](https://docs.rs/dirs/1.0.4/dirs/fn.config_dir.html), but we've since upgraded to [dirs v4.0.0](https://docs.rs/dirs/4.0.0/dirs/fn.config_dir.html).

This can be closed now that https://github.com/rust-lang/rustfmt/pull/5910 was merged.

@calebcartwright I took another look and I think this is good to go 👍🏼 and could be included in the next release, but I don't mind if we want to...
