use APK for PIP

[tuxpeople]

• revert d998700
• add apk magic to fix this:

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.
