Use `happy-dom` again in vitest as it has caught up recently to `jsdom`
in terms of features and it is a much more lightweight solution.
I encountered [one
bug](https://github.com/capricorn86/happy-dom/issues/1342), but it's an
easy workaround until fixed.
I regenerated the lockfile to get rid of the transitive dependencies so
that's why the diff also has some upgrades in it.
In total, this change removes 39 npm dependencies.
