Add proper ominous banner translation (#1692)

Browse source 
The ominous banner is a separate banner type in Bedrock. If we detect the ominous banner pattern, then we set the ominous banner type in NBT. This process is also checked vice-versa, allowing the ominous banner to be pulled from the Bedrock creative menu.
