Test: Fix jest-dom matcher type imports

[alitas]

What I did

Changed the type import path for jest-dom matchers from @testing-library/jest-dom/types/matchers to @testing-library/jest-dom/matchers.

Importing directly from @testing-library/jest-dom/types/matchers seems to be translated as
import { TestingLibraryMatchers } from '@testing-library/jest-dom/types/matchers';
in the build output dist/index.d.ts, which TypeScript can't parse right and causes it to be typed as any when imported.
