yourlabs/python container adds security audit tools

The new version of yourlabs/python docker image, which bundles npm and pip3 on alpine and a bunch of testing tools, was released with bandit and safety baked in.

py-sec-bandit:
  image: yourlabs/python
  script: bandit -v -x commands,tests {posargs:-r src}

py-sec-safety:
