Quick Intro Pip Install wants --break-system-packages on Ubuntu 26.04

[slowrunner]

Just a comment about the introductory "Try It In Three Commands" on Ubuntu 26.04:

"Try It" either requires creating a venv or --break-system-packages so it can't be "Try It" as documented.

ubuntu@u26llpi5:~/U26LLPi5/systests/urml$ pip install urml-validator urml-ros2-runtime urml-llm-bridge
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.
    
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    
    See /usr/share/doc/python3.14/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
