amd: require bitsandbytes>=0.50.0 in the amd extra (fixes ROCm 4-bit NaNs) (#7535)
* amd: require bitsandbytes>=0.50.0 in the amd extra

bnb <= 0.49.2 NaNs at decode shape on every AMD GPU. The ROCm 4-bit GEMV
fix (bnb PR #1887) first ships in 0.50.0, on PyPI since 2026-07-24, so the
old >=0.49.1 floor could still resolve the broken range.

Mirrors the same change made on the pip release branch in #7278.

* amd: cite the 0.50.0 ROCm work accurately in the bnb floor comment

The comment credited bnb PR #1887 as "the ROCm 4-bit GEMV fix" for every
AMD GPU. #1887 decouples blocksize from warp size and fixes a hardcoded
warp size of 32 in kgemm_4bit_inference_naive, which is a CDNA problem by
construction. The RDNA-side work is #1979 (fused 4-bit SIMT GEMM) and
#2012 (RDNA3/4 workgroup resonance). All three first ship in 0.50.0, so
the >=0.50.0 floor is unchanged; only the justification was wrong.

* amd: raise the installer bitsandbytes fallback floors to 0.50.0

* Tighten AMD bnb floor comments

* Keep the amd extra citation and the AMD install guide reference

* amd: do not promise aarch64 a ROCm 4-bit backend it never gets
