Auto merge of #113365 - dima74:diralik/add-deprecated-suggestions, r=workingjubilee

Add `suggestion` for some `#[deprecated]` items

Consider code:
```rust
fn main() {
    let _ = ["a", "b"].connect(" ");
}
```

Currently it shows deprecated warning:
```rust
warning: use of deprecated method `std::slice::<impl [T]>::connect`: renamed to join
 --> src/main.rs:2:24
  |
2 |     let _ = ["a", "b"].connect(" ");
  |                        ^^^^^^^
  |
  = note: `#[warn(deprecated)]` on by default
```

This PR adds `suggestion` for `connect` and some other deprecated items, so the warning will be changed to this:
```rust
warning: use of deprecated method `std::slice::<impl [T]>::connect`: renamed to join
 --> src/main.rs:2:24
  |
2 |     let _ = ["a", "b"].connect(" ");
  |                        ^^^^^^^
  |
  = note: `#[warn(deprecated)]` on by default
help: replace the use of the deprecated method
  |
2 |     let _ = ["a", "b"].join(" ");
  |                        ^^^^
```
