@g-francesca Can you fix or remove the playwright tests? After that, this'll be ready to land!

Yes! Some selectors were still targeting old web components. @avivkeller I added data-testid attributes to the new React components and updated the Playwright locators accordingly. Can you please double-check? TY!

Thanks @avivkeller. So I've updated the HTML element targeted as search-results wrapper (I've targeted the wrong one before by mistake). I tried to run the playwright tests locally, and they're passing.

Can you update https://github.com/nodejs/nodejs.org/blob/main/.github/workflows/sync-orama.yml to use the new API keys?
