Add to handbook doc: ability to override data- attributes for controller, target, action

[lsparlin]

Documentation Changes

I recently encountered an issue where I added Stimulus to a client project and I quickly discovered the data-action attribute was already being listened for and conflicting with the stimulus event expectations. Unable to remove that javascript I read some code and learned how to override these attributes.

To help others who may encounter similar conflicts I'd like to propose adding this process to the Stimulus handbook.

Thanks for your consideration.
