(AB#263705) Fix description for example using [ValidateScript()] (#…

…11180)

Prior to this change, the example description in the article
_How to validate an argument using a script_ declared that
the example validates that the input belongs to a set of
possible values. That description belongs to a different
example, using `[ValidateSet()]`.

This change:

- Corrects the example description to match the code.
- Fixes AB#263705
