Publish new version of `eth-query` with type definitions from this repo

@metamask/controller-utils relies on eth-query, but this package has no type definitions. We've backfilled the type definitions for this package, but they are private to this repo. This means that it's impossible to use the current version of @metamask/controller-utils in another project (like Snaps). We should fork eth-query and publish a new version that contains the same type definitions as here.

I'm going to convert this library to TypeScript and get it looking like our other repos.
