deps: update peerDeps to support React 19 without warnings (#116)

* deps: update peerDeps to support React 19 without warnings

- react 19 is also incompatible with `@testing-library/react` 13, so it needs updating as well, see next commits

* typings fixes required in new version

* update @testing-library/react to compatible 16.1 version

- react 19 support in https://github.com/testing-library/react-testing-library/releases/tag/v16.1.0

(cherry picked from commit ebec40b)
- fixed various merge conflicts:
  - no typings changes as there is no TS on the `v1.0.x` branch
  - no `@types/` updates either
  - isolate surrounding deps changes etc (only update `react`, `react-dom`, and `@testing-library/react`)
