Test: Add local testing (no docker need), working on windows

Problem: User do not want to install docker to test
        and docker is not set for windows already
Solution: Get the script to make the tests locally with current os and
        vim

Log of workflow (6h):
=====================

Test: cloning only last 10 Vader commits locally [tinwin]
Test: run_bash fix local copies and prettify/robustify [tinwin]
Test: Lint tests and fix err treatment in run_bash [Tinmarino]
Test; Windows: Restore the bug that I appended on Linux OLD-PATH env deps [Tinmarino]
Test: bash script first success on Windows (only the script not the tests) [tinwin]
Test: Dirty Backup [tinwin]
