refactor: stop spreading challenge over the node (#44499)

* refactor: stop spreading challenge over the node

Instead of creating a Gatsby node with id of challenge.id, we create a
single node field that has all the challenge data.

While this makes the GraphQL queries more verbose, it means we're free
to create multiple nodes with the same challenge.id.

* test: update time-line test for new GQL schema

* test: update mocks with new GQL schema
