recommend/document basic use of uv

[williamstein]

See https://docs.astral.sh/uv/

A section about uv should be added to https://doc.cocalc.com/howto/install-python-lib.html

It's very easy to install the latest version, make a project, install packages and create a custom kernel. This just all follows exactly the official docs with nothing at all special about CoCalc.

curl -LsSf https://astral.sh/uv/install.sh | sh
mkdir project
cd project
uv init
uv add Hypothesize 'numpy>=1.23'
uv add --dev ipykernel
uv run ipython kernel install --user --env VIRTUAL_ENV $(pwd)/.venv --name=project

uv finally gets Python packaging right, and is clearly a significant leap over everything that came before it...

since this script installs a kernel, shouldn't it be in https://doc.cocalc.com/howto/custom-jupyter-kernel.html ?

It is exactly analogous to this: https://doc.cocalc.com/howto/install-python-lib.html#pipenv-with-a-jupyter-kernel

Also, nobody installs a venv and doesn't want a kernel so they can access it.
