Update PHPStorm metadata to support Intersection Types

[ghostwriter]

This pull request updates the PHPStorm >=2021.3 metadata file to support Intersection Types.

References:

Blog post on PHPStorm 2021.3 release

PHPStorm documentation on advanced metadata mapping

An example of the changes made to the meta file:

- override(\mock(0), map(["" => "@"]));
+ override(\mock(0), map(["" => "@&\ArrayAccess"]));

These changes will enable developers using PHPStorm to take full advantage of Intersection Types when mocking objects.

This will be followed by an additional PR adding the doc comments to indicate intersection types for static analysis tools.

/** 
* @template T of object
* @return T&\Mockery\MockInterface
*/
