Support for the new Angular @let syntax

[Tortila90]

Description

Angular 18.1 introduced the new @let syntax: https://angular.dev/api/core/@let

It differs from the recently added @if or @for, because it doesn't contain any following brackets or parentheses.

As of now any code in a file that comes after @let may not be formatted correctly, especially if there are more @if or @for.

Input

With this new feature, when I give like this input:

@let foo = 'bar';
<div>
  @if (foo) {
  {{ foo }}
}
</div>

Expected Output

I'd like to see this output:

@let foo = 'bar';
<div>
  @if (foo) {
    {{ foo }}
  }
</div>

This is so much needed, if I correctly remember the approximate implementation it should not be difficult to extend keywords list.
