Call for Review for a clarification in keyboard trap rule

Hello Act rules,

This is Call for Review for a clarification in the keyboard trap (standard navigation) rule:
https://github.com/act-rules/act-rules.github.io/pull/1905


This makes explicit the assumption that only one direction is needed, as discussed in CG call last Fall.
This also improve an example, ensuring it actually is a failure.

Call for review ends on January 16th.
