Consider Supporting GraalVM "Innovation" Releases

Hello! I'm guessing you are already working on this, but... just in case... Starting with Graal v25.1 Graal is now detached from OpenJDK releases for non-LTS releases. I think the Graal team is calling the non-LTS releases "Innovation" releases.

## Oracle GraalVM
For Oracle GraalVM 25.1+ we have the following [script-friendly URLs](https://www.graalvm.org/downloads/). For example, v25.1.3 URLs are:
```
curl https://gds.oracle.com/download/graal/25i1/archive/graalvm-jdk-25i1-25.0.3_linux-x64_bin.tar.gz
curl https://gds.oracle.com/download/graal/25i1/archive/graalvm-jdk-25i1-25.0.3_linux-aarch64_bin.tar.gz
curl https://gds.oracle.com/download/graal/25i1/archive/graalvm-jdk-25i1-25.0.3_macos-aarch64_bin.tar.gz
curl https://gds.oracle.com/download/graal/25i1/archive/graalvm-jdk-25i1-25.0.3_windows-x64_bin.zip
```
Interesting that we don't see 25.1.3 anywhere in the URL. On the Oracle website this is described as 25.1 (Innovation). So the `25i1` is probably the version key.

For LTS versions, URLs are unchanged (I think):
```
curl https://download.oracle.com/graalvm/25/archive/graalvm-jdk-25_linux-x64_bin.tar.gz
curl https://download.oracle.com/graalvm/25/archive/graalvm-jdk-25_linux-aarch64_bin.tar.gz
curl https://download.oracle.com/graalvm/25/archive/graalvm-jdk-25_macos-aarch64_bin.tar.gz
curl https://download.oracle.com/graalvm/25/archive/graalvm-jdk-25_windows-x64_bin.zip
```

## GraalVM Community Edition
For GraalVM Community Edition, downloads [are still available on GitHub](https://github.com/graalvm/graalvm-ce-builds/releases).

But the URL scheme has changed a tad:

25.1+:
```
https://github.com/graalvm/graalvm-ce-builds/releases/download/graal-25.1.3/graalvm-community-jdk-25i1-25.0.3_linux-x64_bin.tar.gz
```

Older LTS releases are unchanged (I think):
```
https://github.com/graalvm/graalvm-ce-builds/releases/download/jdk-25.0.2/graalvm-community-jdk-25.0.2_linux-x64_bin.tar.gz
```
Notice that the graal version does not necessarily match the jdk version anymore.

## Happy to Help
Let me know if there is anything I can do to help.

And I'll be so bold to ping @fniephaus from the Graal team to see if he has any tips/corrections.

Start by comparing the Oracle GraalVM and GraalVM Community Edition URL schemes shown in the issue, including the 25.1+ Innovation identifiers and the unchanged LTS forms. Done means Innovation releases can be discovered from both sources while existing LTS URLs continue to work; validate against the concrete Linux, macOS, and Windows examples provided.
