Create a Contributor Guide for New GSoC Participants

[DarhkVoyd]

Description:
With the new season of GSoC approaching, many contributors are joining our community. Currently, there is no guide to help them understand our project structure or how they can contribute effectively. This leads to most new contributors focusing solely on the specification website, often overlooking ecosystem tools like validators, benchmarks etc, which provide impactful opportunities for contributions.

Proposal:
Create a guide that:

1. Explains the role of the JSON Schema specification community.
2. Introduces contributors to the spec website and its purpose.
3. Highlights key ecosystem tools (e.g., Bowtie, HyperJump Validator) and their relevance to the community.
4. Provides guidance on how contributors can get involved in both the spec and ecosystem tools.

This guide will help direct contributors to areas where their efforts can make a significant difference, distributing traffic more effectively across the community's projects.

Thanks DV. What is clear is we can improve on how to better guide new contributors and also GSoC contributors. My proposal is:

1. Improve the global contributing guidelines to better explain to new contributors all the possible ways of contribution, including ecosystem related projects.
2. Improve the current GSoC readme to provide better context and link better with the contributing guidelines.
