Title: fix: "text/html" is not supported.

Hi,

In sample codes, I think `text/plain` should be used instead of `text/html`.
`text/html` is used as content_type, but `text/html` is not supported by the client as below.

In addition, I think this issue had caused #38 issue and `data_raw=` only ignores content_type even if it has a problem. So `data=` should be used in sample codes.

### Supported content types.
```ruby
$ pry
[1] pry(main)> require 'riak'
=> true
[2] pry(main)> cd Riak::Serializers
[3] pry(Riak::Serializers):1> @serializers
=> {"text/plain"=>Riak::Serializers::TextPlain,
"application/json"=>Riak::Serializers::ApplicationJSON,
"application/x-ruby-marshal"=>Marshal,
"text/yaml"=>Psych,
"text/x-yaml"=>Psych,
"application/yaml"=>Psych,
"application/x-yaml"=>Psych}
```
