gs-overview-page: Avoid vertical space fill of the featured carousel
On Fedora Silverblue, by default most of the sections on the explore page are missing, which results in a rather odd layout:
This is caused by there being relatively few apps available out of the box - once you add Flathub it looks much better.
We should probably set a better max height for the banners. Also, can we show more apps on the explore page? It's not like there are no apps available by default...
