Silence PHPStan tautology on setOptions() guard

PHPStan resolves OptionsResolver against the installed version (>= 7.3
in CI), where setOptions() exists, so the runtime method_exists() guard
appears tautological. Ignore the function.alreadyNarrowedType identifier
on that line so the guard remains in place for older OptionsResolver
versions allowed by the composer constraint.
