An expression starting with r#const etc. should be accepted even in edition <=2021.

Fixes #18148.

This was not fixed when testing with edition 2024, I wonder whether that means our check for edition is incorrect...

Do we even need this check anymore at this point? I imagine this was done because our parser was not edition aware at the time

I don't think the parser differentiates between those and other exprs when in macro (although it can be done probably). The entry point is just Expr. So I believe the check is still needed.

Right, the edition gating doesn't matter here my bad.
Thanks!
