Gitpod: Enable webpack dev server

We currently force the static webpack compilation in GitPod. This
behaviour is annoying if someone changes frontend assets, because all of
GitLab needs to be recompiled, which is time consuming.

This enables the normal webpack dev server, but with live reload
disabled. enabling live reload is being tracked here:
