chore(curriculum): fix + test curriculum order (#44366)

* chore(tools): test curriculum order

* chore: update orders

* fix(tests): temporarily ignore cert super

The Relational Databases cert being 'upcomingChanges' is breaking
the tests.

* fix: graphql query here

* fix: use only one meta

* chore: remove unnecessary superOrders

* chore: zero-based indexing

* fix: update mock

* refactor: remove unused fixture
