[Feature] Make CLI handle updating webpack configs

Is your feature request related to a problem? Please describe.
When I upgraded to a new version of dev-Webpack; I almost missed the message about
using "./node_modules/.bin/update-ns-webpack --configs" to update my config file... It scrolled right off the screen.

Describe the solution you'd like
tns webpack clean which would reset the config files...

possibly in addition: tns webpack update which would install @latest of the dev-webpack

Describe alternatives you've considered
None, the idea is to make the cli handle it... 😀

Additional context
Shouldn't have to deal with other tool; the CLI should handle it...

Beginne damit, die CLI-Verarbeitung für tns webpack und den bestehenden Workflow update-ns-webpack --configs zu lokalisieren. Ermittle, ob clean Konfigurationsdateien zurücksetzen sollte und ob update die neueste Version von dev-webpack installieren sollte; abgeschlossen ist die Aufgabe, wenn die unterstützten CLI-Befehle das separate Tool ersetzen, ohne das beabsichtigte Verhalten zur Aktualisierung der Konfiguration zu verlieren.
