Feature request: Support for uv package installer

[gangsthub]

Describe Request:

Official support for https://github.com/astral-sh/uv for faster installs.

uv is an extremely fast Python package resolver and installer, designed as a drop-in replacement for pip, pip-tools (pip-compile and pip-sync), and virtualenv.

It has some limitations, so I don't know if it would be that easy to add it as a "drop-in replacement", depending on the pip features you use currently.

Examples:

version: '2.1'
orbs:
  python: circleci/python@<...>
jobs:
  build:
    executor: python/default
    steps:
      - checkout
      - python/install-packages:
          pkg-manager: uv
