CSS Spanning outdated

[lauramorinigo]

In the example 2, the draft mention the following:
@media (device-posture: folded) and (screen-spanning: single-fold-vertical) { ... }

The screen-spanning is outdated and should be replaced with vertical-viewport-segments:1, same for flex: 1 1 env(fold-bottom); since the newly updated CSS viewport segments media query.
Anyway, we received some feedback from developers that it can be confusing because it looks like vertical-viewport-segment (screen-spanning in this case) it's part of the current Device Posture API but it's not. Therefore the other fix would be to remove it.
Thoughts?
