Dhruv Manilawala 9bb23b0a38 Expect indented case block instead of match stmt (#11033) ...

## Summary

This PR adds a new `Clause::Case` and uses it to parse the body of a
`case` block. Earlier, it was using `Match` which would give an
incorrect error message like:

```
  |
1 | match subject:
2 |     case 1:
3 |     case 2: ...
  |     ^^^^ Syntax Error: Expected an indented block after `match` statement
  |
```

## Test Plan

Add test case and update the snapshot.
