Core: Dedupe aria-query and @testing-library/dom packages

[mrginglymus]

@testing-library/dom was pulling in a fixed version of aria-query@5.3.0. Other references to aria-query are using @^5.3.0 (or similar), which means that many bundles included two full copies of aria-query.

This PR shaves ~200kb off manager/globals-runtime.js (storybook runtime), and the same from test/index.js (storybook browser)

📝 Walkthrough

Walkthrough

Updates dependency constraints: relaxes @testing-library/dom from exact 10.4.0 to caret ^10.4.1 in code/core/package.json, and adds a resolution entry for aria-query@5.3.0 in code/package.json.
