Fix all broken CIs (#7439)

Fix all the broken CIs :p

This includes an ongoing effort to simplify test maintenance by having 1
unique source of truth about metadata and data mocks (that will later be
generated from a unique source of seeds: dev = demo = test)

Regressions:
- Unit line coverage: 60 > 55
- Storybook Pages branch coverage: 40 > 35
We will need to write tests to increase those coverage
- RelationFieldDisplay perf: 0.2ms to 0.22ms > We might have a
regression here
- Removed perf story about RawJSON > We will need to re-add it
