Switch DeepSeek-OCR scripts to vLLM nightly wheels

PR #27247 is now merged to main, so we can use the official nightly wheels
instead of the fork branch.

Changes:
- Replace git+https://github.com/Isotr0py/vllm.git@deepseek-ocr with vllm
- Add [[tool.uv.index]] for https://wheels.vllm.ai
- Keep prerelease = "allow" for nightly builds
- Update docstrings to reflect PR merged status
- Update error messages (remove PR reference)

This should provide faster installation since we're using pre-built wheels
instead of compiling from source.
