Fix scroll-state queries snapped ambiguity

[chrisdavidmills]

Description

In #40290, @LukeAtlas22 points out that our scroll-state queries docs contain an ambiguity. It says:

snapped: Queries whether a container is, or will be, snapped to a scroll snap container ancestor along a given axis.

But the evaluation occurs only on the scrollsnapchanging event, which fires when an element will be snapped, not when it is snapped. Therefore, the above wording needs an update.

This PR provides that update.
