Add python3.11-venv package to Ubuntu instructions

[JPablomr]

Description

This updates the install instructions for Ubuntu24 to include the python3.11-venv package.

I couldn't get the install to work until I installed this package, I was seeing

Error: Command '['/opt/automatic1111/stable-diffusion-webui/venv/bin/python3.11', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

and then it would error out with:

ERROR: Cannot activate python venv, aborting...

Screenshots/videos:

Before:

It didn't work for me. Until I asked chatGPT for help.

The instructions for "ubuntu 24.04" is wrong.
sudo apt install python3.11
needs to be
sudo apt install python3.11-full
as the full version contains the "ensurepip" module

Uninstall python 3.11 and install the "full" version from deadsnakes

EDIT:

Note to self: "do not answer things when you are busy and do not have time to properly think" 🙊

@jmraker do not forget that ChatGPT is not always reliable. ensurepip should be supported by both versions, since it is part of standard library. ensurepip was not the issue, but venv most likely is not included in "standard" version for Ubuntu, since they have python*-venv, so basically both of you are right.

You can use one or the other way. I will double check when I find some time.
