[CHORE] Possibility to create environment with system installed uv

[maruschin]

I encountered an inconvenient dependency on a pre-installed version of Python.
It is very convenient to create an environment with the required version via uv.

IIUC this PR means that instead of:

• uv-managed Python with a uv-managed Python environment

We now allow for:

• system-managed Python that has uv installed, with a uv-managed Python environment

I'm not the most familiar with uv, but would it not be the most reproducible developer experience if uv were to manage everything, including the Python installation? I know we've had issues in the past with inconsistent system installs of Python.

@jaychia it's most like:

• system-installed uv managed Python and Python environment

uv does not depend on Python and can be installed on its own.

Makes sense, thanks for the contribution!
