Bazel 9 compatibility

rules_jsonnet 0.7.2 depends on an outdated version of jsonnet_cpp that is not compatible with Bazel 9:

```
File "/xyz/e039a0d51aa3648f6061154c43aa4253/external/jsonnet_go++http_archive+cpp_jsonnet/stdlib/BUILD", line 9, column 11, in

File "/virtual_builtins_bzl/bazel/exports.bzl", line 40, column 9, in _removed_rule_failure
Error in fail:
This rule has been removed from Bazel. Please add a `load()` statement for it.
This can also be done automatically by running:
buildifier --lint=fix
```

Please bump versions of dependencies.

Start by locating the dependency declarations for rules_jsonnet 0.7.2 and its jsonnet_cpp dependency. Reproduce the failure with Bazel 9, then verify the dependency updates by building the affected Jsonnet rules; done means the removed-rule error no longer occurs.
