Ominous banners generated in outposts show the pattern list

Ominous banners show their last 6 patterns on the tooltip, even though they have 8 patterns (the tooltip can only show 6 of them), and it's useless information as they can't be recreated in Survival mode.

This affects banners generated in outposts and banners dropped by pillagers that have been placed and then mined.

This bug can't be fully fixed due to MC-178410.
