[Feature] GitHub API integration with resource submission form

## Problem
Follow up to the issue #9

## Description
The alternative solution that has been suggested is to allow users to submit a pull request (PR) if they want to contribute a resource.

However, this can be a problem for non-tech-savvy users who may not be familiar with the GitHub platform. Therefore, we should consider using the GitHub API to link our custom-made form with GitHub and simplify the process for the users.

By using the GitHub API, we can authenticate users and create a pull request directly from our custom form. This will enable our users to submit their resources seamlessly without having to navigate through the GitHub platform. I think that this will improve the user experience and encourage more contributions to our resources.

## Implementation

- [x] I would be interested in implementing this feature.
