[1.20.3+] Wrong grass ID mapping

[Sunset-NotFound]

What happened?

Starting from Minecraft1.20.3, Mojang changed the name of grass to short_grass This resulted in all shaders packages being unable to recognize grass, Users cannot solve the problem by modifying the properties file either.

Okay, I haven't looked at the source code and I don't know the actual situation, but currently it's really impossible to fix this issue through the properties file.

Additional context
