<STRUCTURE>_HAS_STRUCTURE biome tag fields should be renamed to HAS_<STRUCTURE>

[TelepathicGrunt]

Example of what I am seeing in 1.20 Yarn BiomeTags class:

Personally, I feel this is a cause where it should break out of the <inner_tag>_<outer_folder> format in favor of cleaner readability.

In this case, I propose HAS_<inner_tag>. Or HAS_STRUCTURE_<inner_tag> which still reads better that current situation
