Disable strict_args warning in Sidekiq

[cwrw]

Context

A new warning was introduced in latest Sidekiq: sidekiq/sidekiq#5071 which will become an error in version 7.0.0.

This is raising errors in the following workers:

VendorAPIRequestWorker
DataExporter

I've added the following tickets to address those later:
https://trello.com/c/VDFAN4u0/2274-rework-vendorapirequestworker
https://trello.com/c/ZpGm6nOH/2275-change-dataexporter-to-use-native-json-types

For now disable this warning

Things to check

• If the code removes any existing feature flags, a data migration has also been added to delete the entry from the database
• This code does not rely on migrations in the same Pull Request
• If this code includes a migration adding or changing columns, it also backfills existing records for consistency
• API release notes have been updated if necessary
• Required environment variables have been updated added to the Azure KeyVault
