drop failing pip package install from the image

[vszakats]

Install seems to be failing:

error: externally-managed-environment

× This environment is externally managed
╰─>
    The system-wide python installation should be maintained using the system
    package manager (apk) only.

    If the package in question is not packaged already (and hence installable via
    "apk add py3-somepackage"), please consider installing it inside a virtual
    environment, e.g.:

    python3 -m venv /path/to/venv
    . /path/to/venv/bin/activate
    pip install mypackage

    To exit the virtual environment, run:

    deactivate

    The virtual environment is not deleted, and can be re-entered by re-sourcing
    the activate file.

    To automatically manage virtual environments, consider using pipx (from the
    pipx package).

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.
