dirs is unmaintained, dirs-next should be used instead.

I would be willing to implement this and submit a PR if it would be accepted.

The advisory now says: "This advisory has been withdrawn and should be ignored. It is kept only for reference."

dirs appears to be maintained now; it isn't very active, but the last activity is more recent than on dirs-next. However, dirs is now at version 4, whereas terminfo depends on version 2. Updating this would help to reduce duplicate crate dependencies for us.

On it.

Done.
