Rename Paragraph long and short and consider wether this is component props at all

[eirikbacker]

Today we have Paragraph, Paragraph variant="short" and Paragraph variant="long".
This means our consumers can make any Paragraph component short or long.

I understand we need short and long in context of i.e. text inside a Card, but I'm unsure wether we want Paragraph component aka. body text to be varying in line height, breaking the typographic flow.
I suggest we make a distinction between what is a text style and what is a typography component.

Also, variant="long" and variant="short" is a bit confusing for me - may be personal opinion, but could density="compact" and density="loose" better? ☺
