[Suggestion] Add parameter for raw returning of the fact

[Evanito]

For use with a chatbot on twitch that doesn't support parsing JSON, it would be useful if we could pass a parameter with our request such as ?raw=True to just get the fact.

Example:
Current: https://dog-api.kinduff.com/api/facts
{"facts":["More than 5,000,000 puppies are born in the U.S. every year."],"success":true}

With flag: https://dog-api.kinduff.com/api/facts?raw=True
More than 5,000,000 puppies are born in the U.S. every year.

Also shoutout from dogdog 🐶

I'm writing Ruby for the first time and also trying to contribute code.

I've added the raw param to facts endpoint. Let me know if it's correct. 👍
