Add examples for each adapter in docs.

[beauby]

Add examples of a sample JSON output for each adapter in adapters.md.

@beauby What kind of examples you looking for?

[beauby]

@mooreniemi Updated the description. I meant examples of a sample JSON output for each adapter. Thanks for noticing the ambiguity of the request!

[mooreniemi]

@beauby NP. I was wondering if this'd cover something I was looking for: examples of custom adapters. I'd like to write one for the Mason hypermedia type. Perhaps a separate issue?

[beauby]

@mooreniemi Yup, please open a separate issue. I'd be happy to help you, we can talk on slack.

@beauby your link is a 404. You probably mean this file: https://github.com/rails-api/active_model_serializers/blob/master/docs/general/adapters.md

@robinboening Thanks, I just edited my post.
