Analyse also dependencies bundle (#6438)
Analyse also dependencies bundle (#6438)

The current `analyze` script only analises the `/src` code. This change leverages new version of `source-map-explorer` that is able to analyse multiple bundles at once, including the  3rd party dependencies bundle which is in my opinion even more important to analyze.
