When checking the Accept header the charset is expected to be utf8 not utf-8

[pkqk]

Expected Behaviour
A request with the HTTP header:

Accept: application/json; charset=utf-8

is accepted as a GraphQL request

Actual Behaviour
The request is rejected with:

HTTP 406 Not Acceptable

Debug Information
I think the check here is wrong and should be looking for utf-8 not utf8.
