`nixpkgs_java_configure` doesn't work with nixpkgs Bazel 7
Describe the bug
It looks like a combination of using nixpkgs_java_configure and Bazel 7 from nixpkgs results in a missing bootstrap toolchain:
flurie@nixos:$ bazel build //... --toolchain_resolution_debug='@@bazel_tools//tools/jdk:bootstrap_runtime_toolchain_type'
Starting local Bazel server and connecting to it...

To Reproduce
I'm migrating a rather large project to Bazel 7, so I don't have a min repro on hand, but I have a feeling a min repro would just be running Bazel 7 from nixpkgs, configuring a Java toolchain with rules_nixpkgs, and using a repo rule like http_archive that uses this toolchain.
Expected behavior The rules_nixpkgs Java toolchain already stands in for the runtime_toolchain_type, so I would expect it to register the bootstrap_runtime_toolchain_type as well since they are very nearly the same thing.
Environment
- OS name + version: NixOS 23.11
- Version of the code: rules_nixpkgs v0.10.0
Additional context Add any other context about the problem here.
Just for reference, also see https://bazelbuild.slack.com/archives/CFB3AE72P/p1704908066268699
The bootstrap toolchain was added as part of bazel 7 (well, as part of rules_java xxx, released together with bazel 7 AFAIK). The fix is to ship some definition for that one too in nixpkgs_java_configure.
