PR #30724 adds a note to "future-incompatible" lints indicating that they will be a hard error in the future, but it would be better to also specify why the change is being made. For example, "this is due to a bug fix, please see issue #123 for details"

There is now more structure to the report, so that you can specify e.g. an RFC/PR/issue number and other explanatory details.

Example message:

```
type-parameter-invalid-lint.rs:14:8: 14:9 error: defaults for type parameters are only allowed on type definitions, like `struct` or `enum`
type-parameter-invalid-lint.rs:14 fn avg<T=i32>(_: T) {}
                                         ^
type-parameter-invalid-lint.rs:14:8: 14:9 warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
type-parameter-invalid-lint.rs:14:8: 14:9 note: for more information, see PR 30742 <rust-lang#30724>
type-parameter-invalid-lint.rs:11:9: 11:28 note: lint level defined here
type-parameter-invalid-lint.rs:11 #![deny(future_incompatible)]
                                          ^~~~~~~~~~~~~~~~~~~
error: aborting due to previous error
```
