Adding CI for testing

Hi everyone,

In this part i have added continuous integration for better testing of the project and maintaining with good quality on the GitHub.

GitHub actions: this is added in my project for checking any changes in the code and integrating it on main branch if it is functioning correctly.

In my Partner project i have: added workflow which will trigger on every push to the main branch and makes pull requests targeting the main branch. It sets up Node.js, installs dependencies, and runs test using the npm test command.

Thank you
