nodejs 16 docker images for debian stretch no longer work due to EOL python versions

[wraithgar]

The nodejs 16 docker images for stretch and stretch-slim can not build using the versions of npm or node-gyp that ship with nodejs 16. debian stretch ships with an EOL python, outside the scope of what npm and node-gyp currently support.

Possible Solution

As per nodejs/node-gyp#2392 (comment) the docker image is going to need to manually update the python version on the image to 3.6 or newer in order to work.

Steps to Reproduce

See npm/run-script#40 for an example

Additional Information

Stretch has stopped receiving security updates but is in LTS support until June 2022
