@GuillaumeGomez Two tests (json-bom-plus-crlf.rs and json-bom-plus-crlf-multifile.rs) contain E0308 explanation as json, like:

rust/src/test/ui/json-bom-plus-crlf.stderr

Lines 1 to 17 in 823ff8c

{"message":"mismatched types","code":{"code":"E0308","explanation":"This error occurs when the compiler was unable to infer the concrete type of a
variable. It can occur for several cases, the most common of which is a
mismatch in the expected type that the compiler inferred for a variable's
initializing expression, and the actual type explicitly assigned to the
variable.
For example:
```compile_fail,E0308
let x: i32 = \"I am not a number!\";
// ~~~ ~~~~~~~~~~~~~~~~~~~~
// | |
// | initializing expression;
// | compiler infers type `&str`
// |
// type `i32` assigned to variable `x`
```

So you should also update these stderrs.

Improve E0308 error message wording

Hi folks,

I made [a post on Reddit](https://old.reddit.com/r/rust/comments/fmi11x/consider_linting_rusts_documentationerror_text/) about how (IMO) the docs/error messages can be a bit intimidating, one thing led to another, and I was encouraged to submit a Pull Request if I felt I could re-phrase the error message that I used as an example.

So that's this Pull Request. Open to any feedback or style changes, and I understand this is subjective.

(On another note: I am happy to see [this message was recently improved](rust-lang#69139) in `master`, so it's already better than it is in stable Rust 1.42.0.)

Ideally the last sentence could be split into at least two: [sentence explaining the inferred type.] [Sentence explaining explicit type.] [Sentence that summarizes that "this is bad," and why.]

But I'm not sure how to do so; I'm wary of writing something that turns out to be technically incorrect.
