Story

In the current Experimental module federation build, the exposed module should be configurable. For now only the '.' module is added and is fixed to the package main entry, which doesn't support alpha packages containing the new frontend system generated assets.
At least we should by default include also the alpha code as an additional module.

Background

This change would be needed to be able to use the upstream CLI to build frontend plugins using the new frontend system as dynamic frontend plugins.
