Define contributing guidelines

[Cli4d]

Dependencies

This issue is dependent on #67

Problem Statement

We need to link contribution guidelines to the github org level so that potential contributors can easily know whether or not this project fits with what they can do and also for us to get more contributors.

Additional Information

The current contributing file I found is this https://github.com/OpenTermsArchive/engine/blob/main/CONTRIBUTING.md
This doc accurately covers the details of the contributor workflow but leaves out some contributor details

What happens if this is not addressed

If not addressed we may lose potential contributors who visit the GitHub org

Recommended Action Items

• Add a priority label to this issue (OTA team)
• Add a project label to this issue
• Discuss with a Community Manager at Open Terms Archive
• Discuss with the Open Terms Archive team
• Make a new issue in the project repository

Potential solutions [draft]

It would be great if we could add some details for it to answer the following question:

• Which repositories can I contribute to?
• What roles of contribution are available? Developer, Designer, Project management, etc.
• Where do I start?

I am not sure which repository this issue can be transferred to

Transferring to Docs, which should have a dedicated Contributing section.
