[TypeDeclaration] Fix abs() returns on ReturnTypeFromStrictTypedCallR…

…ector (#5652)

* Create demo_file.php.inc with return type for abs function

Function [abs](https://www.php.net/manual/en/function.abs.php) returns int or float (depends on input parameter). For PHP versions without support union return types this rule should only add return type into docBlock.

* return

* return

* fix
