Module imp deprecated and removed in Python3.12

While trying to implement CI:

ImportError while importing test module '/builds/placoto/placoto-cli/tests/TestCase1.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/local/lib/python3.12/importlib/__init__.py:90: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)

Refactor in favor of importlib.
