Add vscode tailwind extensions & prettier tailwind linter, sort tailwind classes

[pat-s]

These are the ones that cause the auto-sorting in all my recent PRs. If we would all use these (and sort all classes once), we'd have a predictable and consistent order of tailwind classes.

• Added prettier checks to docs/ and web/ enforcing the sorting. As the release process in plugin-prettier has some issues currently, I've used :next to move on

Can we add linting as well then? Not everybody uses VSCode.
