[Docs]: Setup consumer chain in tests without connecting to a provider. #2206
Description
Summary
It would be great to have some documentation on how to integrate the ccv module into genesis in already established unit and integration setups like the one we have at Evmos. Below is the PR adding it to our chain test setup but would be nice to have this explained in docs so future standalone chains are aware that adding the ccv module in their app.go will require additional configuration in unit / integration testing suites.
