chore: Make N-0 MSRVs explicit

This will require a version bump every release but over-releasing these
packages is likely a lot better than over-releasing the N-3 packages,
which we won't have to do anymore after this.

My hope is the `auto` value will be approved and stabilized and then we
won't have to over-release anymore.
