Describe the bug

Trying to use Sentry.capture_exception(error) to capture a StandardError and send it asynchronously , but it failed to enqueue and reported

async event sending failed: Unsupported argument type: StandardError.

The failed reason can be found here: https://github.com/rails/rails/blob/v6.0.3.4/activejob/lib/active_job/serializers.rb#L28. It seems like ActiveJob 6 can't serialize an Exception object

Expected behavior
Event should be compatible with ActiveJob 6+

Environment

• Ruby Version: 2.7.2
• SDK Version: 4.1.4
• Integration Versions (if any):
• Rails 6.0.3.4, Sidekiq 6.1.2

Sentry-ruby Config

    Sentry.init do |config|
      config.breadcrumbs_logger = [:active_support_logger]
      config.before_send = lambda do |event, hint|
        event.modules.clear
        event
      end
      config.async = lambda { |event, hint| SentryJob.perform_later(event, hint) }
    end
