"Reindent Lines" doesn't work correctly with square brackets

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: Reproduced in 1.135.0 and 1.136.0-insider
- OS Version: Linux Mint 22.3 - Xfce 64-bit

Steps to Reproduce:

Go to Command Palette -> Reindent Lines on a Rust file that looks like this:
```
fn test() {
let x = vec![
1,
2
];

let y = foo(vec![
1,
2
]);

let z = 3;
}
```

Result:
```
fn test() {
let x = vec![
1,
2
];

let y = foo(vec![
1,
2
]);

let z = 3;
}
```
