Copyright endpoint does not include thumbnail field when image name is changed

[emmachughes]

Thumbnails in the copyright info are only included if the image's contentName parameter equals Image:

https://github.com/cerpus/Edlib/blob/cd932c0180b2bf725800ed8c426ce60972aa3d7a/sourcecode/apis/contentauthor/app/Libraries/H5P/H5PCopyright.php#L193-

The h5p-core library uses this logic, too:

https://github.com/h5p/h5p-php-library/blob/b5f527e140c17da2792283d369f621e9b3f969ff/js/h5p.js#L1247

However, contentName is not a machine-readable identifier for the content type, it is a freely editable text field that can be altered from the H5P editor:

Thus, naming the image anything other than Image excludes it from having an associated thumbnail in the copyright info.

Some other method of establishing the content type should be used instead.
