frontend: use vite's mechanism for env variables to fill window.envir…

…onment

That we don't have locally cached environment.js files breaking the development setup.
Sadly we still use vue-cli to run our tests, so there the vite mechanism does
not work and we have to maintain one additional environment.js.

In production, we compose the environment.js anyway in the configmap, thus we don't
have to consider the production case in dev-environment.js.

Now we can also remove the check in index.html.
In a production environment, you have to check yourself that you have all the needed configurations
set.
