Deduplicate the CrateInfo provider

[UebelAndre]

It seems there should be a single source of truth here? The only difference seems to be in the docs for the parameters:

diff --git a/rust/private/providers.bzl b/rust/private/providers.bzl

 )

Any reason to not unify these? Note that users will still be able to load the provider from the same path.

Oh good catch, I think this was added by accident. LGTM!
