chore: remove vite-plus (for now)

It seems like we're currently using vite-plus solely for running tests. It caused issues in the past that forced us to migrate away from it in most places (vite fmt, vite lint running postinstall and causing severe delays). It currently crashes on Windows arm64 machines. It is also explicitly said:

> Vite+ is not yet stable and should not be used in production.

With that in mind, vite-plus does not provide a lot of value to the project at the moment and therefore I propose removing it for now.
