Support for pyproject.toml and uv in python buildpack

[amardeep]

We (like a lot of new projects) use pyproject.toml to specify dependencies and uv to lock them. Please support pyproject.toml and uv.lock for building python containers.

Great news! Support for pyproject.toml and uv is now available in Public Preview for the Python Buildpack.

Note on requirements.txt:
If you are using requirements.txt file, you can opt-in to use uv as your package manager by setting the environment variable GOOGLE_PYTHON_PACKAGE_MANAGER=uv. For Python 3.14+ projects, uv is set to be the new default installer when a requirements.txt is present.
