When writing a Quarkus extension, it would be nice if the developer had a list of the existing BuildItems they can use.

For example, if I want to deploy a ServletContainerInitializer, I'd use a ServletContainerInitializerBuildItem. Finding the exact build item is a hard task and it would be nice to have a search mechanism to find this information

We have a page generated at https://quarkus.io/guides/all-builditems however it's a bit annoying to find what you need there. It would be nice if we had a list of potential builditems in an IDE tool window (bonus points if including those that are not available in the project)
