Issue Description

In Sentry, there's a section for Sidekiq exceptions that records the configuration. It looks like in Sidekiq 7, this is not serialized/inspected in a way that actually conveys any useful information.

Reproduction Steps

Record an exception with 5.7.0 and observe the "Sidekiq" section of the exception.

Expected Behavior

I would expect this section to either not exist in the report or to show Sidekiq settings such as queues, concurrency, timeout, etc.

Actual Behavior

_config is printed as something like #<Sidekiq::Config:0x00007f447c676368>
