[Bug] Incorrect types in cosmos_db_trigger decorator

### Expected Behavior

When using the `start_from_time` and `start_from_beginning` parameters, no typing errors should occur.

### Actual Behavior

These fields (`start_from_time` and `start_from_beginning` ) are both typed as `Optional[time]`. It seems to me like it should be:

```
start_from_beginning: Optional[bool] = None,
start_from_time: Optional[str] = None, <-- is this str or datetime? It is unclear to me
```
Also, the fields are not correctly documented in microsoft learn:
