In #168816, we removed support for Python/Ruby/WASM to reduce the
support burden of GraalVM languages that, arguably, are not really being
used.
However, the way that `pkgs.graalvmCEPackages.mkGraal` function works
right now doesn't allow passing a custom sources file, that would allow
someone to compile GraalVM with the additional products (e.g.: Python).
This PR adds this possibility.
So if someone wants to create a custom graalvm11-ce derivation with
Python support, for example, they can do something like this:
```nix
let
graalvm11-ce-custom = pkgs.graalvmCEPackages.mkGraal {
config = {
x86_64-linux = {
products = [ "graalvm-ce" "python-installable-svm" ];
arch = "linux-amd64";
};
};
defaultVersion = "22.0.0.2";
javaVersion = "11";
platforms = "x86_64-linux";
sourcesPath = /home/someone/graalvm11-ce-sources.json;
};
in
{
environment.systemPackages = [ graalvm11-ce-custom ];
}
```
Those additional languages does not seem to really have much usage
(e.g.: none in nixpkgs). For example, Ruby is pretty much broken for all
environments for quite sometime already, however nobody seemed to border
enough to fix it. They also add a good amount of size to the derivation.
So let's remove them. It should be really easy if someone still cares
for them and want to add them back on their own system: just use the
`mkGraal` function (that we export) to generate their own version of
GraalVM with all extra features they want.
