Fix triton-kernels dependency for vLLM nightly

Add explicit triton-kernels dependency from git to resolve vLLM
nightly build dependency resolution issue.

Error was: "Package `triton-kernels` was included as a URL dependency.
URL dependencies must be expressed as direct requirements"

Solution: Add triton-kernels as direct git dependency pointing to
v3.5.0 subdirectory as required by vLLM nightly.
