Cleanup (#730)

* Cleanup

- Cleans various caches after build to minimize size of intermediate images
- Only copy necessary stuff over (e.g. the "patches" directory was there as well as other things like maven directory)

* In preparation for 24.7 this already removes 27.0.0

It does not yet add 30.0.0
