Issue Description

I wanted to update Faraday on an older application, but the sentry-raven dependency was preventing it. YAK SHAVING, HERE WE COME!

Reproduction Steps

• In the application's Gemfile, replace sentry-raven with sentry-rails and sentry-ruby and run bundle
• Get a failure message about the Gemfile.lock being locked to an older version of Faraday
• Run bundle update faraday
• Update config/initializers/sentry.rb
• Grep the project for references to Raven
  • .capture_exception is easy enough...
  • Raven.user_context doesn't seem to have an equivalent. Consult migration guide, see mention of Sentry.set_user method instead
  • Download the RDoc for both sentry-ruby and sentry-rails into, e.g., Dash
  • Search for set_user in the RDoc for both sentry-rails and sentry-ruby

Expected Behavior

Documentation that describes the shape of data that MUST/SHOULD/MAY (see RFC 2119) be passed to the Sentry.set_user method.

Actual Behavior

The Sentry.set_user method does not appear in the docs at all.
