Add "Explore" button

[sfrandsen]

In Spring Boot Initializer there is a nice "Explore" button next to the "Generate" button, it shows what will be generated and is a great tool to create snippets without actually generating the entire project code.

A feature like this would be nice in quarks code :-)

Hi @sfrandsen,

Thanks for taking the time to suggest improvements :)

This feature has already been mentioned here: https://github.com/quarkusio/code.quarkus.io/issues/1099

This is indeed something that would be a plus, but the amount of work/charge on server it requires compared to the added value never decided us to go for it. I would be happy to review and help if you want to contribute it.

Cheers!
