docs: add section for filtering open-source projects by programming language and skill level

[devBitt]

The getting-started-with-open-source repository provides a compilation of resources for new contributors.
Currently, it presents a general list of projects and tips, but lacks a dedicated section that helps users filter or search for open-source projects by programming language, skill level (beginner/intermediate/advanced), or type of contribution (documentation, code, design, etc.).

Proposed Change

Add a new section (for example under “Resources → Project Lists”) titled:
“Filter projects by language & difficulty”
It should include a small table or interactive checklist allowing users to identify projects matching e.g. “Python – Beginner – Documentation”, “JavaScript – Intermediate – Code”, etc., with links to example issues/projects.

Why this matters

• Helps newcomers find contributions that match their skill set or interests.
• Reduces friction for prospective contributors and increases participation.
• Adds structure to a resource repository, improving UX and clarity.

Suggestions for Implementation

• Add a markdown file: filter-by-language.md or a new subsection in compilation_of_open_source_resources.md.
• Format as a table: | Language | Skill Level | Contribution Type | Example Projects |
• Provide 3-5 example entries for each row.
• Ensure links are valid and redirect to project issue lists labeled “good first issue”.

Additional Notes

• Ensure accessibility: maybe a column for “friendly first issue label present”.
• Use same style and formatting as existing content (check repository’s CONTRIBUTING or style guide).
• Review existing issues to confirm this suggestion isn’t already open.
