[Bugfix] Require triton >= 3.0.0 to resolve issue with MoE and TP>1

[tdoublep]

Fixes #6103 via triton-lang/triton#4295

This would make #6140 redundant but let's see if bumping Triton causes any issues in CI.

Hmm closing this for now since it seems to conflict with torch version currently being used:

INFO: pip is looking at multiple versions of torch to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install -r requirements-cuda.txt (line 7) and triton>=3.0.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested triton>=3.0.0
    torch 2.3.0 depends on triton==2.3.0; platform_system == "Linux" and platform_machine == "x86_64" and python_version < "3.12"

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

we will need to wait for torch to go to Triton 3.0.0 i guess

To update this, we will need to wait for torch 3.0 to release, followed by xformers, vllm-flash-attn and flashinfer.

I think #6140 can serve as a solution for triton <3.0.0.
