Ed Page 831847e5f0 fix(rustc): Always pass --edition to rustc 
On [Internals](https://internals.rust-lang.org/t/idea-rustc-cargo-should-warn-on-unspecified-edition/20309),
the idea came up for warning on unset Edition.
I am working on the cargo warning but if rustc ever wants to do so,
they'd be blocked on cargo ensuring `--edition` is always set.
Hence this change.
