Remove version from JS to improve compatibility with cache busting

Cache busting requires the version parameter (e.g., *.js?v=10.3.6) to change in order to invalidate the cached file. Relying on manually updating this value can lead to stale assets being served.

So we do not have to depend on someone always updating this value, just remove it altogether, so that the cache busting param is refreshed on a full cache clear.
