chore: project more accessible and collaborative for all participants.

[lucioerlan]

I am very interested in this project and would like to see how I can contribute. I put together these contribution guidelines, what do you think? 🚀

This pull request adds important documentation features to the project.

• It includes a CONTRIBUTING.md file that describes how to contribute to the project.
• It also includes a PULL_REQUEST_TEMPLATE.md file that shows how to open a pull request to add a new feature or fix a bug.
• In addition, it includes a SECURITY.md file that describes how to report security issues in a responsible manner.
• I have refactored the nodejs.yml file to make the steps in its action clearer.

These files will help make the project more accessible and collaborative for everyone.
