Room list: center focus outline of room list item (#32637)

* fix: in room list item, replace bottom padding by top and bottom

Outline focus is not aligned when only using a padding bottom. Replace
by a padding-top and a padding-bottom.

The padding top is not added on the first item and the padding bottom
neither on the last item

* test: update snapshot

* test: update storybook screenshot

* test: update screenshot

* chore: use css var instead of duplicating the logic

* chore: add new stories for first and last item case

* test: add new screenshots following the new stories
