E0204 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0204.rs

Error E0204 needs a span_label and updated title, changing it from:

error[E0204]: the trait `Copy` may not be implemented for this type; field `ty` does not implement `Copy`
  --> src/test/compile-fail/E0204.rs:17:10
   |
17 | #[derive(Copy)] //~ ERROR E0204
   |          ^^^^
src/test/compile-fail/E0204.rs:17:10: 17:14 note: in this expansion of #[derive(Copy)] (defined in src/test/compile-fail/E0204.rs)

To:

error[E0204]: the trait `Copy` may not be implemented for this type
  --> src/test/compile-fail/E0204.rs:17:10
   |
17 | #[derive(Copy)] //~ ERROR E0204

Note: I'm not sure the "expansion of..." part is helpful, you could also remove that.

Seems related to #35382

@munyari Are you also working on the bonus part of this issue?

@KiChjang - the expansion note should be gone now, so I'm going to close this.
