External API: Accept header not specified correctly
Steps to reproduce
According to https://docs.opencast.org/develop/developer/api/usage/, the HTTP accept header must be set to:
The format is specified to use application/<version>, or application/<version>+<format> to also specify the required format.
This is not correct: application/<version> was never supported so this is a error in the API specification.
Changing this will not break clients as it never worked.
