Add (vertical) alignment options for the Header and Extensive Text element

I want to be able to vertically align the text content inside a Header/Extensive text element (similar to how I can do it for the Button element.

The problem

There is currently no way to vertically align the content inside a text element. The inline text options allows you to only align horizontally.

Possible solution

Add the possibility to align the content inside to text element (similar tot the Button element)
