Introduce usage of venv

[miroslavpojer]

• Introduced usage of venv in action yml code.
• See example output comment below.

Summary:

• GH action setup-python is required when on runner is not up to date python version only.
• Venv can fix the situation when on the runner, there is a strict strategy about a Python install and limited usage of pip.

Closes #90

Release notes:

• Added code to workflows to run python in venv instead of master one installation.

See the output when no venv used and no python setup defined:

`Current Python version: 3.12.3 Minimal required Python version: 3.11.0 Python version meets the minimum requirement of 3.11.0 error: externally-managed-environment

× This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.

See /usr/share/doc/python3.12/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification. Error: Process completed with exit code 1. `
