[DOC] E2E / Playwright implementation

[frenchki]

Change in the documentation

Hi, it would be good to have an example on how developers should use @openfeature/react-sdk when using it together with a E2E testing tool like Playwright. It isn't really mentioned in any documentation and would help developers integrate openfeature faster into their applications. For example how to flip the flags to different values inside E2E tests if using the InMemoryProvider?

Hey @frenchki, we have some docs for component-level testing but nothing for E2E tests yet. This poses some challenges as it currently depends on the provider you're using. However, we may want to look into supporting E2E testing use cases directly within the SDK. Perhaps we could support some kind of override via local storage (or something similar).
