Move eth-query back from devDeps to deps

[FrederikBolding]

Explanation

In #1815, @metamask/eth-query was moved from deps to devDeps under the assumption that this would be safe because the dependency is only used for types. This assumption is false as the type import is shipped in utils.d.ts and will be attempted to be resolved in packages that consume the library. This in turn causes build errors like: Error: node_modules/@metamask/controller-utils/dist/util.d.ts(2,27): error TS2307: Cannot find module '@metamask/eth-query' or its corresponding type declarations.
