nit: we use packages 📦 right?

Perhaps it'd be better to name this in the plural. When there is an unstable numbered edition, this will be allowing that as well as the future edition. And generally, at least on the rustc side, we prefer to name feature flags in the plural.

Sure! My thinking was that there is only ever one edition allowed in a manifest, but I'm fine either way.
This adds support for the "future" edition which was added to rustc in rust-lang/rust#137606. To enable support for unstable editions, this introduces a new `unstable-editions` cargo feature. The intent is that instead of having a new feature for each edition that we reuse this feature for all new editions. I don't see a particular reason we should have a separate one for each edition, and this helps a bit with scalability and simplifies some of the edition process. This also includes a change to rework `supports_compat_lint` explained in the comment.
