feat(openapi-react-query): Introduce createQuery

[zsugabubus]

Changes

Fixes #1807. Instead of adding a dedicated useQueries function I would like propose a general query builder solution, this way not only useQueries, but all similar functions are covered for free.

~~Unfortunately, I could not resist and introduced two other (minor) changes on my way to the new feature. I'm happy to remove/split them. Please see changeset.~~

How to Review

• Please check proposed API changes first.

Checklist

• [x] Unit tests updated
• [ ] docs/ updated (NO, missing for createQuery)
