It would be very helpful to set the resolver version in a virtual workspace based on the edition field being added in RFC 2906. This has been requested several times and has caused some confusion for some users.

That is, if you have:

[workspace]
edition = "2021"
members = ["foo"]

Then this will default workspace.resolver = "2"

The logic for determining the version is here. It should also check the workspace edition. This should also be gated on workspace-inheritance on nightly.
