Consider changing to & for let bindings #40402

This is a fix for #40402

For the example
```
fn main() {
    let v = vec![String::from("oh no")];

    let e = v[0];
}
```

It gives
```
error[E0507]: cannot move out of indexed content
 --> ex1.rs:4:13
  |
4 |     let e = v[0];
  |             ^^^^ cannot move out of indexed content
  |
  = help: consider changing to `&v[0]`

error: aborting due to previous error
```

Another alternative is
```
error[E0507]: cannot move out of indexed content
 --> ex1.rs:4:13
  |
4 |     let e = v[0];
  |             ^^^^ consider changing to `&v[0]`

error: aborting due to previous error
```
Also refer to #41564 for more details.
