removed array typehinting for $payloayd

[povilas]

you must be able to send not only arrays, but also simple strings as JSON $linkedin->put("/posts/xxx/category/code", "job");

last example in https://developer.linkedin.com/documents/api-requests-json

Array data gets converted to JSON, so you don't have to create and pass around JSON strings in PHP.

Well, that doesn't change.
