Instructions' validation

Any inconsistency in regards to instruction format will result in a 400 status code and a corresponding error message.

For example, payload as such:

{
    "source": "universal",
    "url": "https://www.example.com/",
    "render": "html",
    "browser_instructions": [
        {
            "type": "unsupported-wait",
            "wait_time_s": 5
        }
    ]
}

Will result in:

{    
    "errors": {
        "message": "Unsupported action type `unsupported-wait`, choose from 'click,fetch_resource,input,scroll,scroll_to_bottom,wait,wait_for_element'"
    }
}
