Update Sentry integration

[jrhoads]

The older gem sentry-raven has been deprecated. There is a migration guide to using the sentry-rails suite of gems and their configuration https://docs.sentry.io/platforms/ruby/migration/

Benefits (from the guide):

• Unified Interfaces With Other SDKs: The design of sentry-raven is outdated compared with our modern Sentry SDKs. If you also use other Sentry SDKs, such as Sentry's JavaScript SDK for your frontend application, you'll notice that their interfaces are quite different from the one provided for sentry-raven. The new sentry-ruby SDK provides a more consistent user experience across all different platforms.
• Performance Monitoring: The Sentry Ruby SDK includes performance monitoring, which you can enable if you haven't already as (discussed here).
• Future Support: sentry-raven has entered maintenance mode, which means it won't receive any new feature supports or aggressive bug fixes.
• Better Extensibility: Unlike sentry-raven, sentry-ruby is built with extensibility in mind and will allow the community to build extensions for different integrations/features
