[relent0r]

Description of the proposed changes

This PR fixes a small error in the AI platoon build templates. The T2LandAmphibious was set to build the Aeon Aurora instead of the Blaze.

Testing done on the proposed changes

Validated that the correct unit was being built post change

Additional context

According to the file history this error has been there for YEARS :D I even went back and checked the original SCFA lua files, the error was present then too.
