Resolve "Increase retry count for the SyncSeatLinkRequestWorker"

What does this MR do?

This MR changes the retry count for the SyncSeatLinkRequestWorker from the default of 3 to 20. You can see a breakdown of the retry waiting times on this Sidekiq wiki page.

This will allow the worker to retry across multiple days in the event that there is a connectivity issue like recently happened between the customers app and the license app.

Screenshots

Before:

pry(main)> SyncSeatLinkRequestWorker.sidekiq_options

After:

pry(main)> SyncSeatLinkRequestWorker.sidekiq_options
=> {"retry"=>20, "queue"=>"sync_seat_link_request", :backtrace=>true}
