missing type object in phpdoc ItemDataProviderInterface::getItem()

[julienbornstein]

API Platform version(s) affected: all

Description
ItemDataProviderInterface::getItem() $id argument could also be an object

eg: an item with an identifier of type Ramsey\Uuid\UuidInterface

---

How to reproduce

I created a dummy project so you can check: https://github.com/julienbornstein/api-uuid/blob/master/src/DataProvider/FooDataProvider.php#L16

Run the project then do a GET request on /foos/:id

eg: http://127.0.0.1:8000/foos/3fa85f64-5717-4562-b3fc-2c963f66afa6

Possible Solution
Updating the phpdoc. I created a PR for that #4039
