[1.21] PaucalBlockStateAndModelProvider doesn't work if texture has different RL from default

[slava110]

Hi. After 1.21 update PaucalBlockStateAndModelProvider doesn't allow texture for block model to have different path from default one. This is probably caused by not passing BlockModelBuilder into simpleBlock method in the code.
I've experienced it with HexCasting datagen when it tried to generate block models for slate tiles, akashic ligature, slate block. They have their textures named or placed differently from default resource location (slate tiles, for example, has its texture placed in hexcasting:block/deco/slate_tiles instead of hexcasting:block/slate_tiles).
Here is 1.20.1 code:

Here is the same code in 1.21:
