Fix example docs

- Edited the examples of resource hashes to be what would actually be used (while it's defined as hash like "$example = { stuff => 'it'}" in the module itself, in actual use when included it works like an attribute, i.e. "example => { stuff => 'it' }" ). 

- Removed the 'puppet' markdown, as markdown then colored the hashed attributes as not being correct, which is probably why it was shown the way it was in the first place.
