docs: update showcase data of InfraQL (#6445)

* Update users.tsx

Hi, we have changed our product name from InfraQL to StackQL and we have gone all in with Docusaurus - including the marketing site, docs and blog (previously it was just the docs and blog), authored a few plugins on npmjs as well if you are interested, love your work!

* fixes
