Grape::ContentTypes::CONTENT_TYPES is not available anymore.

Hi everyone,
While reviewing the ProducesConsumes class, I came across a reference to Grape::ContentTypes::CONTENT_TYPES. In the newer version of Grape, this has been replaced by Grape::ContentTypes::DEFAULTS, as highlighted in the diff below:
Diff of lib/grape/content_types.rb
Additionally, here is the faulty code that caused our workflows to break:

grape-swagger/lib/grape-swagger/doc_methods/produces_consumes.rb

Line 10 in a5e2575

args.flatten.map { |x| Grape::ContentTypes::CONTENT_TYPES[x] || x }.uniq

This is a breaking change and it triggers the following error when trying to access the documentation url:
uninitialized constant Grape::ContentTypes::CONTENT_TYPES

Resolved in #940.

I released 2.1.1.

Thank you!
