This initially may look like a downgrade, but this is caused by how
upstream is tagging versions.
Before they would have the GraalVM having its own version (e.g. 22.3.1),
and each version would support multiple JVM versions (e.g. 11, 17, 19).
Now each release supports only one JVM version (e.g.: 21), and they
track the same version as the JVM.
They also changed packaging, making all sub-products (e.g.: GraalPy,
GraalRuby, etc.) standalone, so they do not depend in GraalVM anymore
and have their own version. Thanks to this change, we will need to
repackage everything.
To simplify, this commit will remove all sub-products and only care
about the GraalVM/Native Image (that is back to GraalVM itself) part.
Other commits will re-added each sub-product.
