Enable TypesScript for Playwright (#587)

Transform Playwright related files to Typescript and introduce temporary
configuration files `.eslintrc-ts`, `jest.config-ts.js` and `tsconfig.json`
that must be removed when whole package is transformed into Playwright.

Due to missing TypeScript support in the rest of the package, `*.spec.tsx`
and `*.story.tsx` file do not have complete types and might not be compatible
with strict type checking that should be introduced in #394.

The reason for such change is parallel work on transformation to TypeScript
and on Playwright tests.
