Improvement/module federation initial load perf improvements

[JBWatenbergScality]

Component:

ui/shell-ui

Context:

Metalk8s UI was beforehand bundling a certain amount of dependencies within it's remoteEntry bundle (due to the eager flag being set on).
This was consequently slowing down UI loading time.

Summary:

This PR improve UI performance by a very high factor (on application where Metalk8s UI is deployed aside of 2 other UI project I've noted a drop of initial loading time from 4.3 seconds to 1.3 seconds, with react being in dev mode so In prod I would expect an even better improvement).
