Document using a password manager during set up is the best practice

Goals

Test that using a password manager (ex. 1password) works when setting up Fleet and logging into Fleet.

In the "Running the Fleet server" docs: Document that using a password manager is the best practice when setting up Fleet: https://fleetdm.com/docs/deploying/server-installation#running-the-fleet-server

This is because, if you forget your password, you will have to wipe the database or redeploy Fleet.

@RachelElysia do you have the time to take this on during your on-call rotation? Please let me know if not.

@edwardsb heads up, this is the issue associated with the "User created their account but then forgot their password..." request you brought to product office hours on 2022-09-22: https://docs.google.com/document/d/1fKUvDOGLhGgeZ9DLBEAJ5HIHOB7sLa6WZTrlPQSxH6Y/edit

We decided to make sure password managers work as expected during set up and document this as best practice. This way, during set up with customer/POC we can point to these docs as best practice.
