Deprecate typing imports off Dict, List, etc.

From Python 3.9 onwards, you can directly use the built-in collection types for type annotations:
i.e.

```python
def process_items(items: list[str]) -> dict[str, int]:
```

is now possible,
vs before we standardized around

```python
from typing import List, Dict
def process_items(items: List[str]) -> Dict[str, int]:
```

We should shift away from use of typing module
