Errors in setup scripts on WSL Ubuntu 20.04

Following the instructions found here.

Firstly python is not linked as python3, simple fix is to change the line in 0-test-compile.sh to:
python3 -m py_compile packages/*-SAMPLE_CODE-1.0/application.py

Secondly 3-build-container.sh is failing on the gzip command somewhere:

=> => naming to docker.io/library/code_asset                                                                                                              0.0s

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them
