David Peter 77ae0ccf0f [red-knot] Infer subscript expression types for bytes literals (#13901 )

## Summary

Infer subscript expression types for bytes literals:
```py
b = b"\x00abc\xff"

reveal_type(b[0])  # revealed: Literal[b"\x00"]
reveal_type(b[1])  # revealed: Literal[b"a"]
reveal_type(b[-1])  # revealed: Literal[b"\xff"]
reveal_type(b[-2])  # revealed: Literal[b"c"]

reveal_type(b[False])  # revealed: Literal[b"\x00"]
reveal_type(b[True])  # revealed: Literal[b"a"]
```

(https://github.com/astral-sh/ruff/issues/13689#issuecomment-2404285064)

- New Markdown-based tests (see `mdtest/subscript/bytes.md`)
- Added missing test for `string_literal[bool_literal]`
