[Bug] Incorrect types in cosmos_db_trigger decorator

[syberen]

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:

Hi @syberen, thanks for the catch. start_from_beginning should be bool, and start_from_time should be str. I've linked a PR with these changes. However, since we're currently in a release freeze with the holidays and this is a minor fix, release ETA is January.

The properties are mentioned in the documentation linked, but they're under the Configuration section. I agree though that the wording for the Decorators and Configuration sections is misleading. I'll work to get that updated, so that the V1 and V2 properties are accurately displayed.
