Fix for GitHub Actions failing for GCC build tools

GitHub Actions failing for GCC build tools

Ref: #22

GitHub actions for the GCC build is failing with an error saying
'python3-distutils has no installation candidate'.
This package is not available in the ubunutu package version 24.04.
The action has been set to runs on ubuntu-latest which was using 22.04
version earlier has switched to use 24.04 version since last 2 days.
So to fix the issue updated the runs on parameter in .yaml file
to use 22.04 version of ubuntu.
