Create a Github Action to generate quickstarts for Quarkiverse extensions

Description

Create a Github Action to generate quickstarts for Quarkiverse extensions using a Quarkus Codestart:

• This codestart can contain complex examples and multiple languages
• The action will generate the application in zip in the given set of languages and buildtools and upload it to the GitHub release page

In the future we could also imagine having a link to code.quarkus.io to generate that particular extension (it would hide the extension selection part).

@ia3andy https://github.com/quarkiverse/quarkus-github-action might be useful for that. I still have to more extensively test it and work on the documentation.
But if you're using it, that will be a good incentive for me :).
