[BUG] FVDB `build_requirements.txt` has incorrect specifications compared to build_environment.yml

[DanielHabib]

build_requirements.txt requires: torch >= 2.2.0+cu121 build_environment.yml requires: pytorch::pytorch=2.4.0

Hi @DanielHabib

Thanks for pointing that out, I hadn't caught that! I've fixed that up and removed torch from the build_requirements.txt because the Docker image we use comes with the pytorch version we need. Thanks
