Allow triton==3.0.x for fp_quantizer (#6447)
Tested with triton==3.0.x and the kernel tests pass so adding as an
allowed version.
Triton 2.3.x is not well supported on arm64. Triton 3.0.0 is supported
on arm64 and it appears the fp8 kernel works fine with triton==3.0.0 so
this simplifies usage on arm hosts (GH200).
