Rollup merge of #61263 - GuillaumeGomez:valid-html, r=Manishearth 
Don't generate div inside header (h4/h3/h...) elements

Fixes #60865.

According to the HTML spec, we're not supposed to put `div` elements inside heading elements (h4/h3/h...). It doesn't change the display as far as I could tell.

8bb094dac5 Add more detail to type inference error 
When encountering code where type inference fails, add more actionable
information:

```
fn main() {
    let foo = Vec::new();
}
```

```
error[E0282]: type annotations needed for `std::vec::Vec<_>`
  --> $DIR/vector-no-ann.rs:2:16
   |
LL |     let foo = Vec::new();
   |         ---   ^^^^^^^^ cannot infer type for `T`
   |         |
   |         consider giving `foo` the type `std::vec::Vec<_>` with the type parameter `T` specified
```

We still need to modify type printing to optionally accept a
`TypeVariableTable` in order to properly print `std::vec::Vec<T>`.

This distinguishes `Option` and `Result`-returning doctests with implicit `main` method, where the former tests must end with `Some(())`.
