Update dependencies in new-lexeme-special-page.
In the README you can find guidelines on how to update the dependencies.
- Given the progress on T314470, evaluate if we can by now update to Vite 3, and if that is possible: do so and also update the README
- This was indeed possible and has been done.
If there are any issues, create a subtask.
If there are open dependabot PRs then either merge them, or close them, or create a task if they need more work and comment the Phabricator Task-ID there.
