When pasting a guide URL in any social media (including chat apps, like Telegram), the preview image displayed is a static image (eg. https://quarkus.io/guides/rest-client-reactive):

It would be nice if the guide title were printed in that preview image (it could be generated during the build) so we could customize it in the <meta property="og:image" content="https://quarkus.io/assets/images/quarkus_card.png"> entry on each guide page
