Thanks for starting the work on these!

Ideally, we'd love to get native speakers' eyes on these translations before merging them in to ensure that they're correct. It would also be great if you could add to the description the languages you've translated and how you created these translations.

[mohankumarhr]

For these translations, I used Google Translate and the Cambridge Dictionary websites as the main tools also I've mentioned the languages which i have translated and I’m happy to incorporate any additional feedback. Let me know if you need any further information or adjustments from my side!

[raclim]

Awesome, thanks so much for adding these! If you know any folks who are proficient in those languages feel free to tag them! I'll try to do so as well!

@mohankumarhr @raclim I found an error in this PR. The translations in the languages I know (English, French, Portuguese, Hindi, and Korean) indicate that the changes are based on this line: "By signing up, you agree to the terms of the p5.js publisher's Terms of Use and Privacy Policy." However, it should be changed to "By signing up, you agree to the p5.js Editor's Terms of Use and Privacy Policy."

I believe "publisher" should be replaced with "editor." Please let me know your thoughts.

After giving it some thought on how we want to handle translations, I think we might want to move away from accepting large submissions with a lot of different languages, and gear towards 1-2 languages per submission. Ideally, the 1-2 languages should be ones that the contributor should know and speak natively to ensure that we're getting proper translations. The reason for this shift is that I feel that we should encourage moving away from machine translations, and to have PRs be as ready for submission as possible.

I'm going to close this one for now—I'm sorry that we couldn't get this in, but please feel free to resubmit this PR with translations for any languages that you personally know!
