Describe the bug

When scanning a class containing properties with PHP native union or intersection types, these will always be flagged as not having a docblock even when a docblock is present.

Code sample

class Foo { /**  * This is fine.  *  * @var string|integer  */ public $correct_not_missing_docblock_union; /**  * This snippet gets flagged with "Missing member variable doc comment (Squiz.Commenting.VariableComment.Missing)"  *  * @var string|integer  */ public string|int $BUG_missing_docblock_with_union_type; /**  * This is fine  *  * @var InterfaceA&InterfacB  */ public $correct_not_missing_docblock_intersection; /**  * This snippet gets flagged with "Missing member variable doc comment (Squiz.Commenting.VariableComment.Missing)"  *  * @var InterfaceA&InterfacB  */ public InterfaceA&InterfacB $BUG_missing_docblock_intersection; }

To reproduce

Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcs test.php --standard=squiz --sniffs=squiz.commenting.variablecomment
3. See error message displayed

--------------------------------------------------------------------------------------------- FOUND 2 ERRORS AFFECTING 2 LINES --------------------------------------------------------------------------------------------- 17 | ERROR | Missing member variable doc comment (Squiz.Commenting.VariableComment.Missing) 31 | ERROR | Missing member variable doc comment (Squiz.Commenting.VariableComment.Missing) --------------------------------------------------------------------------------------------- 

Expected behavior

That the docblocks would be recognized correctly and no "missing docblock" errors would be thrown.
