Update questionhelper.rst

hello,when running the example as it is, a deprecation message is shown (i'm on PHP 8.1.6). the deprecation message says that ``trim(): Passing null to parameter#1 ($string) of type string is deprecated``.what if we add a normalizer that returns an empty string when the entered value is `null` otherwise returns the user's intial input. with this suggestion, the example works great
