[NeoForge 1.21.1] Missing painting variants in minecraft:placeables breaks painting placement

[EnderTurret]

Environment details: NeoForge 21.1.83 on Minecraft 1.21.1 with Builders Crafts & Additions 2 2.1.0

Here's the relevant excerpt from the log:

[29Nov2024 17:36:00.133] [Worker-Main-15/ERROR] [net.minecraft.tags.TagLoader/]: Couldn't load tag minecraft:placeable as it is missing following references: 
	buildersaddition2:summer_field (from mod/buildersaddition2)
	buildersaddition2:modern_shard (from mod/buildersaddition2)
	buildersaddition2:skargard (from mod/buildersaddition2)
	buildersaddition2:ocean_horizon (from mod/buildersaddition2)
	buildersaddition2:steve_portrait (from mod/buildersaddition2)
	buildersaddition2:promotional (from mod/buildersaddition2)
	buildersaddition2:herobrine_portrait (from mod/buildersaddition2)
	buildersaddition2:enderman_approaching (from mod/buildersaddition2)
	buildersaddition2:winter_forest (from mod/buildersaddition2)

If you really want it, the full log is here.

The actual cause of this issue is Builders Crafts & Additions missing all of its painting variant definitions. I've created a sample data pack which fixes this problem by simply adding these painting variants.

This is technically a duplicate of #84, but that issue has been closed and (I assume) forgotten.
