[HOLD] Enable OCR in configs

[peetucket]

We have various repos with feature flags for OCR work that need to be enabled in all environments when ready:

• Argo has Settings.features.ocr_workflow
• Infra Integration tests has Settings.ocr.enabled
• Preassembly has Settings.ocr.enabled

Go through shared_configs and update these all to true when ready for all environments.

HOLD in production until Andrew returns in early July.

Eventually we'll want to remove these feature flags entirely, because we won't be turning this functionality off, but we'll wait till things have been running successfully in prod for a bit to do that.

Current state as of 7/22/2024:

• OCR off in Argo in stage and prod (on in stage and qa)
• OCR off in pre-assembly in prod (on in stage and qa)
• OCR on for both stage and qa in integration tests

OCR was enabled in stage for pre-assembly and integration tests on 7-22-2024 but it is currently not working.
