[Popover] Should we add a paragraph and intent colour on popovers?

[Bibisirius]

Should we add a paragraph on popovers? In most cases, only 1 title and 1 paragraph are used in a popover. To make it easier to implement this case and to move on more quickly: should we include a paragraph by default in the popover? ✅ Yes, the request makes sense

Do we provide intent colour for popover? ✅ Yes, the request makes sense
