Export to GNOME Builder

[sonnyp]

Once an idea is mature - it would be neat to export and open it in GNOME Builder.

This would need a project template with the build system, license, etc. Where the code, XML and css files get copies into. Also git should be initialized maybe.

Maybe gnome-builders template (engine) could be used. There is the idea to source that out into a command line tool. https://github.com/vala-lang/valdo/issues/21#issuecomment-1119139839

We should also optionally have Blueprint, and libportal in the exported project

@sonnyp and me discussed that today. We concured that we parse the source code (via regex or something that parses to an AST), adapt it to remove the Workbench specific parts and export that.
