Missing popper arrow padding support in Popover component makes arrow ugly

[a3kov]

Describe the bug Popover currently doesn't support passing arrow padding option, which is natively supported in popper 2.x

To Reproduce If you look at https://flowbite.com/docs/components/popover/#description-popover The arrow there only looks nice because of the ml-2 on the button icon. While providing workaround for the missing padding support, this also makes the icon appear "disconnected" as it's too far from the text

Expected behavior Popovers should support arrow padding natively. We should not be forced to use button icon margin
