Fix: Translation of "Web editor"

[adityagarg06]

Fixes #2322

Changes:
I have changed the translation of the "web editor" in the translation.json files of the following languages: it, ja, uk-UA, zh-TW.
De has the same translation as In English, so I didn't change that.

I have verified that this pull request:

• has no linting errors (npm run lint)
• has no test errors (npm run test)
• is from a uniquely-named feature branch and is up to date with the develop branch.
• is descriptively named and links to an issue number, i.e. Fixes #123

Thanks for working on this!

I think I'm still not completely sure about the best way to handle this, but since "p5.js Web Editor" has been translated into several languages already I'm down to have this in for now!
