Python package manager uv is now available for builds with zero configuration

Vercel now uses uv, a fast Python package manager written in Rust, as the default package manager during the installation step for all Python builds.

This change makes builds 30-65% faster and adds support for more dependency formats. In addition to requirements.txt or Pipfile, projects can now declare dependencies with a uv.lock or pyproject.toml file.
