Support Torch 2.4 (required for Intel Gaudi 1.18.0)

Is your feature request related to a problem? Please describe.
InstructLab 0.19.3 and its dependencies limit PyTorch to <2.4.0. Intel Gaudi software 1.18.0 just came out. It comes with a custom build of Torch 2.4.0. We need to use the new version for performance improvements and better Gaudi 3 support.

Describe the solution you'd like
Please lift the restrictions to either torch>=2.3.0,<2.5.0 or torch>=2.4.0,<2.5.0.

Additional context
I'm aware that it's not a trivial change. IIRC some instructlab subpackages have a upper version limit as well. Several 3rd party packages like vLLM and flash-attn may need to be updated, too. It might be easier to start with torch>=2.3.0,<2.5.0 everywhere, then set torch>=2.4.0,<2.5.0 in instructlab CLI last.
