Issue:
datadog_monitor support for event-v2 monitors
### Summary

Datadog is deprecating the v1 event monitors in favor of a new v2 monitor type as documented https://docs.datadoghq.com/events/guides/migrating_to_new_events_features/ with the date of 6/30/2022 as the end date of v1 monitors.

They have been sending us emails about this, and I thought it was just a query change but it turns out that we need to set the type passed to the api to `event-v2 alert` instead of `event alert`

I have verified that this support can be added by adding the new event type into [datadog_monitor.py](https://github.com/ansible-collections/community.general/blob/main/plugins/modules/monitoring/datadog/datadog_monitor.py) and have the changes pushed to our fork and will PR from there
