Describe the bug
Currently in my Rails application I don't require ActiveJob framework and on app initialization I get the error uninitialized constant ActiveJob.
I suppose the railtie should check if ActiveJob::Base is defined and then mix Sentry::Rails::ActiveJobExtensions to ActiveJob::Base

To Reproduce
Comment require 'active_job/railtie' in config/application.rb

Expected behavior
No errors

Actual behavior
raising of uninitialized constant ActiveJob error

Environment

• Ruby Version: 2.7.2
• SDK Version: 4.1.4
• Integration Versions:
• Rails 6.1.1
