Translate the "Donate" page

The "Donate" page is currently only available in English. This was first reported in the core library repository: https://github.com/processing/p5.js-web-editor/issues/3356

You can see that there is the English donate.mdx here: https://github.com/processing/p5.js-website/tree/main/src/content/text-detail/en

But this file is missing in each of the other supported language trees:

• https://github.com/processing/p5.js-website/tree/main/src/content/text-detail/es (assigned)
• https://github.com/processing/p5.js-website/tree/main/src/content/text-detail/hi (completed)
• https://github.com/processing/p5.js-website/tree/main/src/content/text-detail/ko - (completed)
• https://github.com/processing/p5.js-website/tree/main/src/content/text-detail/zh-Hans (completed)

Please comment below if you'd like to work on one of these translations. To avoid duplicating work, please wait until a maintainer tags you and confirms you can work on it. Then, you can make a PR referencing this issue. To ensure translation quality, reviewers for these PRs would also be great to have so even if a language you're interested in working on is already in progress by someone else, please comment here anyway and a maintainer will tag you when those PRs are ready for review!

Don't hesitate to comment even if you're not sure where to start 🌼
