wrong sourcetypes for some datasets

[pong-rearc]

eg datasets/suspicious_behaviour/crowdstrike_stream/admin_weak_password_policy/admin_weak_password_policy.yml

is marked with sourcetypes:

• 'XmlWinEventLog:Microsoft-Windows-Sysmon/Operational'

should be crowdstrike:identities

there are others besides this example. all the ones I found so far are in the crowdstrike stream folder, so not sure if other datasets are affected.
