Version 5.11.0

Breaking changes

• Dropped support for Python 3.9. Python 3.10 or newer is now required.

Features and Improvements

• Releases are now built, tested, and published to PyPI from GitHub Actions via
  Trusted Publishing (OIDC) when a release tag is pushed. The ia pex binary
  is built and smoke-tested in CI and attached to the GitHub release.
• Modernized development tooling: the codebase is now formatted with
  ruff format (enforced in CI), CI installs dependencies with uv, and tests
  that hit archive.org are marked with a network marker so the offline
  suite can be run with pytest -m "not network".

Documentation

• Clarified that the retries_sleep upload argument is in seconds.
