Thanks @Keshav-0907 for working on it.

Hi @TanviKumar and @Divyansh013, we updated or merged some of the docs after @Keshav-0907 translated them. Could you take a look at this PR and see if some of the already translated work could be helpful for your translation on the following 4 docs:

• Contributor Guidelines
• Steward Guidelines
• Contributing to the p5.js Reference
• WebGL Contribution Guide

We can either merge this PR or close it to avoid confusion. Please share your suggestion with us about how to handle this PR.
