Rename methods and update docs

This is a minor update to the named methods for the following:

- s/desired_capabilities/capabilities
- s/driver_options/capabilities

Since they are all the same thing we should keep the name the same
throughout the feature.

Updated docs to match / be a little bit clearer

Also updated the Gemfile for selenium-webdriver.
