protoc-gen-doc Issue #541: Add 'edition' support

The problem was highlighted in #541

What is Changing? The plugin's response has been changed so that its supports working with the edition.

How is it Changing? The changes are quite simple. Two fields were added to the plugin's response: MinimumEdition and MaximumEdition. Also the SupportedFeatures flag has been changed to CodeGeneratorResponse_FEATURE_SUPPORTS_EDITIONS. An example of simple proto file that use editions added.

What Could Go Wrong? Perhaps the innovations in the syntax of the message fields will somehow be poorly handled, but in the added simplest example Milk.proto everything works as it should. In addition to this simple example, I can say that on my work project, a large proto file generated the documentation correctly.

@pseudomuto Hello. Can you please review this PR?

@Ekrekr any chance you can give this a review and merge? It seems like a relatively small change to me that would unblock many teams that want to try editions.
