Generic DOM utils parameters

[janbiasi]

• getComponentByDomNode(node) as Button is now getComponentByDomNode<Button>(node)
• the same thing for getComponentByDomNodeAsync<Button>(node).then(b => ... )
• and also for findComponents<Button>(buttonGroup)
• this change is not breaking as the default generic parameter value is GondelComponent so the casting should work as usual.

Cool 👍- one last question is it still possible to call getComponentByDomNode(node) without setting the generic? and if yes will the result be of type GondelComponent?

Yes for sure it is! That's the default behaviour, short example:

// button is of type 'GondelComponent'
const a = getComponentByDomNode(buttonNode);

// button is of type 'Button'
const b = getComponentByDomNode<Button>(buttonNode);

Sidenote: I didn't see any documentation regarding the dom-utils, I think we should expand the documentation in the next steps for better usability.
