Cannot list container repository registries and images on Geo secondary

Summary

!41846 (merged) seems to have introduced package tracking, but broke the pages for Geo secondaries as the Package::CreateEventService attempts to write even in readonly databases (i.e. Geo)

Steps to reproduce

  1. Set up a Geo primary and secondary
  2. Set up container registry replication for Geo (optional, you can also reproduce just by going to the page, without tags)
  3. Go to a project's Container Registry page, observe the error:

image

What is the current bug behavior?

Container registry repositories and images don't work on Geo secondaries.

What is the expected correct behavior?

Container registry repositories and images should be visible

Possible fixes

Make the Package::CreateEventService aware of read-only databases.
