sugg: suggest the usage of boolean value when there is a typo in the keyword

Fixes rust-lang#100686

This adds a new suggestion when there is a well-known typo

With the following program

```rust
fn main() {
    let x = True;
}
```

Now we have the following suggestion

```
error[E0425]: cannot find value `True` in this scope
 --> test.rs:2:13
  |
2 |     let x = True;
  |             ^^^^ not found in this scope
  |
help: you may want to use a bool value instead
  |
2 |     let x = true;
  |             ~~~~

error: aborting due to previous error
```
