So I took an early look at this bump and there is a bunch of changes upstream that we will need to adapt. To start they changed the way they do versions so this is why it seems that we are "downgrading" the version instead of upgrading: the versions now match the JDK version that GraalVM is based on. Also, thanks to this change all URLs are changed.

Also, each of the sub-products (e.g.: GraalPy) are now released independently from the GraalVM main releases and have their own version (it is on 23.1.0 right now, but I expect that they diverge in the future). They also seem to be self contained and not rely in having GraalVM installed anymore, so we can just stop bundling all the packages together in a "super" derivation as we do right now and just split each sub-product in its own package. Thanks to this change, they also don't ship jar anymore, they are all in .tar.bz2 format that should make our lifes easier.
