Add Panther to log destinations docs

[noahtalerman]

Goal

I want to know how to send query results from Fleet -> Panther.

How?

• Add a Panther section to the log destinations docs: https://fleetdm.com/docs/using-fleet/log-destinations
  • This section explains how to use Fleet to send query data to Panther

@chris-mcgillicuddy do you have the capacity to take on writing this guide?

For technical questions, I think @edwardsb is a great resource. Ben authored the Snowflake and Splunk sections.
