Spike: investigate removing src from pf npm packages

currently, the various packages published to npm pf-react all include the src directories which bloat the published pkg size to 6.05 MB https://www.npmjs.com/package/@patternfly/react-core?activeTab=code

it also does create scenarios where products could be importing from our src directories, then their own custom typescript configurations will result in compiled typescript different than the PF distributions. (and possibly build errors for the product)

Would it be possible to remove the src from the pf packages without requiring further breaking changes from the pf packages? If so, this could be possibly framed as a bug fix. That's the goal of this spike.

Jira Issue: PF-26

Inizia esaminando come vengono pubblicati i pacchetti pf-react e confronta i loro contenuti npm, in particolare le directory src incluse. Verifica se la rimozione di src influirebbe sugli import esistenti o sulle configurazioni TypeScript personalizzate; il lavoro è completato quando vengono documentati la fattibilità, i rischi di compatibilità e le eventuali modifiche necessarie ai pacchetti.
