The `fields-relationship` test suite is disorganized to the point of
being unusable. This makes it very difficult to digest at a high level
and add new tests.
This PR cleans it up in the following ways:
- Moves collection configs to their own standalone files
- Moves the seed function to its own file
- Consolidates collection slugs in their own file
- Uses generated types instead of defining them statically
- Wraps the `filterOptions` e2e tests within a describe block
Related, there are three distinct test suites where we manage
relationships: `relationships`, `fields-relationship`, and `fields >
relationships`. In the future we ought to consolidate at least two of
these. IMO the `fields > relationship` suite should remain in place for
general _component level_ UI tests for the field itself, whereas the
other suite could run the integration tests and test the more complex UI
patterns that exist outside of the field component.
