ReturnType<...> idiom obscures reference docs for public APIs

[dckc]

What is the Problem Being Solved?

When a type such as CosmosInterchainService are defined using the typescript ReturnType<...> idiom, vs-code hover shows the type as expected, but the reference docs (CosmosInterchainService) don't show the methods and stuff; they just show a link to the prepareCosmosInterchainService function.

This is convenient during development, but for external APIs, the indirection is obscure.

Description of the Design

Write out the type long-hand, and use satisfies or some such to ensure that the prepareCosmosInterchainService matches.

Security / Scaling / Upgrade Considerations

none. docs only.

Test Plan

I can't think of anything beyond manual review.
