the application/logout+jwt media type

Issue #1484 resolved
Andrii Deinega created an issue

https://openid.net/specs/openid-connect-backchannel-1_0-07.html indicates the “application/logout+jwt” media type was registered in the IANA "Media Types" registry although says that the “typ“ header parameter should be set to “logout+jwt“.

It may make sense to tell the “application/“ prefix should (or must) be omitted.
