Documentation fails to mention `group_notifications` is only for metrics monitors

[mccartney]

The documentation on group_notifications field of sumologic_monitor:

(Optional) Whether or not to group notifications for individual items that meet the trigger condition. Defaults to true.

fails to mention the setting is only (?) available to metrics monitors.

For log monitors you get apply-state error:

Error: {"id":"05N4E-X22Q9-QLTFD","errors":[{"code":"monitors:invalid_group_notification_configuration","message":"Separate notifications are not supported for Log monitors","detail":"Separate notifications are not allowed for Log Monitors. Please use group notifications instead."}]}
