Add support for consecutive `@cases` in Angular templates `@switch` blocks.

angular/angular/pull/66210 will add support for consecutive cases in a `@switch` block. It would be awesome if prettier can follow-up closely for the support.

eg: 

```
@switch (case) {
  @case (0)
  @case (1) {
    <div>case 0 or 1</div>
  }
  @case (2) {
    <div>case 2</div>
  }
  @default {
    <div>default</div>
  }
}
```
