Add support for intersect typehints (&) in PEAR.Commenting.FunctionComment

PEAR.Commenting.FunctionComment does not recognize intersect typehints

     /**
      * Inject a service into the container mock.
      *
      * Adjust `has('service')` and `get('service')` returns.
      *

      * @param mixed $service

     protected function injectServiceInContainer(MockObject $container, string $serviceName, $service) : void
     {

Return type is unaffected so it looks like sniff considers & to be pass-by-reference symbol of parameter name.

Quite likely it happens in other places with variable names after type declaration too, like with inline @var
