sapi/phpdbg: fixed ZPP type violation by using 'h' ZPP specifier instead of 'H'

This aligns the behaviour with what the stubs say.
And even if one fixes the stubs the behaviour is not identical due to missing indirect handling.

This indicates that using objects is never done, so do the easy fix of changing the ZPP specifier.

Closes GH-20465
