How to use `remote_java_repository` with a JDK release where Java home is nested?

I'm trying to use `remote_java_repository` with GraalVM releases on MacOS.

When extracting the package the layout is of the form:
```
└── Contents
├── Home
│   ├── bin
│   │   ├── java
│   │   ├── javac
```

There are no top level symlinks into the nested `bin` directory as can be seen in the Zulu JDK releases that `remote_java_repository` is normally used with.

Would it be possible to make this rule configurable so that the path to the Java home inside the extracted distribution can be customized?
