chore: whats new dialog (#9622)

Adds a new dialog option for whats in new in Unleash items. This can be
tiggerred by setting `popout` to true when configuring the items.

To do this without setting fire to the code, I've also needed to
refactor the NewInUnleash components:

- NewInUnleashItem becomes a dumb item that decides if a dialog or
tooltip should be rendered and controls that render state
- The child item in NewInUnleashItem has been moved out into
NewInUnleashSideBarItem, which feels a bit better since that is a
distinct UI element from the popup
- NewInUnleashDialog now exists, which is a dialog version of the popup.
Meaningfully different to ask for a new component
