Constrain numba test dependency

[gabe-engineers]

What changed

• Add numba>=0.59.0 to the test dependency set.
• Regenerate src/diffusers/dependency_versions_table.py.

Why

On Python 3.12, a clean uv pip install -e ".[test]" can resolve:

librosa==0.11.0
└── numba==0.53.1
    └── llvmlite==0.36.0

llvmlite==0.36.0 only supports Python <3.10, so the test dependency installation fails even though Diffusers supports Python >=3.10.

Numba 0.59.0 is the first release with Python 3.12 support. The existing CUDA Dockerfiles already preinstall newer Numba and llvmlite versions before installing diffusers[test]; this change expresses the compatible Numba lower bound in the test dependencies themselves.

Closes #14067.

Validation

• Reproduced the failure from a fresh upstream clone using Python 3.12.2 and uv 0.11.24.
• After this change, uv pip install -e ".[test]" completed successfully in a clean Python 3.12 environment.
• The resolved versions were numba==0.65.1 and llvmlite==0.47.0.
• uv pip check passed for all 113 installed packages.
• Regenerated the dependency table and confirmed a second generation produced no changes.
• git diff --check passed.

Checklist

• Used Codex to help draft/check this change; I reviewed the diff manually.
• Read the contributor guideline and the AI agent guide.
• Reviewed the diff against .ai/review-rules.md.
• Issue: closes uv pip install -e ".[test]" fails on Python 3.12 due to incompatible numba/llvmlite resolution #14067.
• Docs: not applicable; this only updates test dependency metadata.
• Tests: no unit test added because this is dependency resolution metadata. Validated with:
  • uv pip install -e ".[test]" on Python 3.12.2
  • uv pip check
  • dependency table regeneration idempotency
  • git diff --check
