borrowck: name the correct type in error message

[tamird]

Closes #36407.

But this error also occurs for arrays:

fn main() {
    let x = [Box::new(0)][0];
}

error[E0508]: cannot move out of type `[std::boxed::Box<i32>; 1]`, a non-copy array
 --> src/main.rs:2:13
  |
2 |     let x = [Box::new(0)][0];
  |             ^^^^^^^^^^^^^^^^
  |             |
  |             help: consider using a reference instead `&[Box::new(0)][0]`
  |             cannot move out of here

r? @arielb1 -- I'm not familiar with this area of the code, perhaps you could suggest how to differentiate between slices and arrays?

[arielb1]

The type is available right here on b.ty.sty.

[tamird]

This should be good to go.

[arielb1]

Can you maintain the bug! on b.ty.sty == ty::TyArray and ik == Kind::Pattern?

[tamird]

Sure, done.
