maangchi: aggregate rating data is not retrieved because it has moved into a referenced entity

[jayaddison]

Pre-filing checks

• I have searched for open issues that report the same problem
• I have checked that the bug affects the latest version of the library

The URL of the recipe(s) that are not being scraped correctly

• https://www.maangchi.com/recipe/yuringi

Discovered during review of #905.

The results you expect to see

The overall rating of 5 from the referenced AggregateRating in the page HTML should be returned:

        {
            "@id": "/recipe/yuringi#sso/recipe/95471/rating-aggregate/5/233/1/5",
            "@context": "https://schema.org",
            "@type": "AggregateRating",
            "ratingValue": 5,
            "ratingCount": 233,
            "worstRating": 1,
            "bestRating": 5
        },

...

The results (including any Python error messages) that you are seeing

>>> s.ratings()

    raise SchemaOrgException("No ratingValue in SchemaOrg.")

This looks like a case where entity-based lookups may be required, similar to #895.
