Is `on_worker_boot` still required in Rails 5.2?

[lleger]

The README says:

For web servers that fork, be sure to reconnect after forking (just like you do with ActiveRecord::Base)

But this is no longer required in Rails 5.2: rails/rails#31241

Does this still apply to Multiverse or can it be dropped if using Rails 5.2+?

Hey @lleger, from the PR, that looks to be the case. Updated the readme. Thanks!
