Attributes object doesn't support _merge_objects flag because it's not an array

[JamesFX2]

foreach() argument must be of type array|object, bool given in vendor/braze/sdk/lib/Normalizer/UsersTrackPostBodyNormalizer.php on line 106

The attribute body supports a semi-undocumented feature called _merge_objects
Attributes being https://www.braze.com/docs/api/objects_filters/user_attributes_object an object in the array of attributes sent by the Track Users endpoint.

Use to update a nested custom attribute
Use to update a object in an array of objects

@JamesFX2 thanks for opening this issue! Could you provide some example code so I can see which part needs to be fixed?
