[StefH]

Describe the bug
The RecognizedMetadata in the api-docs.yml is missing property "recognizer_identifier"

To Reproduce
Use Docker Analyzer

POST this body:

{
    "text": "john@smith.com",
    "language": "en"
}

Response is:

[
    {
        "analysis_explanation": null,
        "end": 14,
        "entity_type": "EMAIL_ADDRESS",
        "recognition_metadata": {
            "recognizer_identifier": "EmailRecognizer_140076591272816",
            "recognizer_name": "EmailRecognizer"
        },
        "score": 1.0,
        "start": 0
    },
    {
        "analysis_explanation": null,
        "end": 14,
        "entity_type": "URL",
        "recognition_metadata": {
            "recognizer_identifier": "UrlRecognizer_140076591273824",
            "recognizer_name": "UrlRecognizer"
        },
        "score": 0.5,
        "start": 5
    }
]

Expected behavior
The "recognition_metadata" contains an extra property named "recognizer_identifier".
