[Andrzej Śliwa]

would be great to link to stimulus documentation and guide from readme

Hi Andrzej,

first of all thanks for your contribution on the stimulus integration!

There is already a link here: https://github.com/komposable/komponent#stimulus-integration

Do you think we should add more links? I think it's best to link only to the repository since other URLs may change at some point.
