chore: Bump Celery to 5.1.2

[john-bodley]

SUMMARY

At Airbnb we're testing using the celery beat command for dedicated reporting. The issue we're running into is the application fails to beat after a period of time. Though there is no guarantee that this is an issue with Celery, I thought it was at least prudent to bump Celery as per the release history we're at least 12 months behind the latest release.

TESTING INSTRUCTIONS

CI and verified that our docs, scripts, etc. have Celery 5.x compliant CLI commands.

Celery 5.0 introduces a new CLI implementation which isn’t completely backwards compatible.
The global options can no longer be positioned after the sub-command. Instead, they must be positioned as an option for the celery command like so:
