Title: Removed incorrect Strong Parameters example

The first Strong Parameters additional parameter permit example does not work, as it attempts to shovel a symbol into a hash (specific error `undefined method '<<' for {}:ActionController::Paramters`). Removed that code snippet, replacing it the block style example that had previously followed.
