Add `without_pip` option to `_.python.venv`

[sbidoul]

Hi,

The new _.python.venv mechanism sounds very good.

Would it make sense to add a without_pip option for creation, mirroring python -m venv --without-pip ?

Virtual environment without pip are viable nowadays, since pip has a --python option.

It’s particularly viable when pip is not used at all. Because uv is upon us and all that 😄

Yes, I would like this as well. And to revisit the possibility of using rye, which uses uv under the hood because rye is now being developed by astral - the well-backed creators of ruff, uv etc... It seems to me that they'll be the one-stop shop for python, if they aren't already.
