Fix rails 6 content type deprecation warnings
What does this MR do?
I had enough of seeing:
DEPRECATION WARNING: Rails 6.1 will return Content-Type header without modification. If you want just the MIME type, please use `#media_type` instead.
in my rspec outputs
Time to do something about it and just follow the suggestion: use #media_type
Screenshots
Example running $ bundle exec rspec ee/spec/requests/api/nuget_packages_spec.rb
