feat(datasource): add GraalVM version datasource

[zeitlinger]

Changes

Adds a new graalvm-version datasource to fix compatibility issues with Oracle GraalVM versions in the mise manager.

Context

The mise manager currently uses JavaVersionDatasource (Adoptium API) for all Java variants, including oracle-graalvm-* prefixes. However, Adoptium API versions are incompatible with GraalVM, causing failures like
prometheus/client_java#1734.

Solution

Created a new graalvm-version datasource that:

• Queries the mise-java.jdx.dev API for Oracle GraalVM releases
• Filters results by vendor (oracle-graalvm) and image type (jdk/jre)
• Uses system detection to map Node.js platform values to API parameters
• Supports explicit platform specification via query parameters

Package naming format:

• oracle-graalvm-jdk?system=true - Auto-detect current system
• oracle-graalvm-jre?os=macosx&architecture=aarch64 - Explicit platform
• oracle-graalvm-jdk?releaseType=ea - Early access releases

System detection mappings:

• Architecture: ia32→i686, x64→x86_64, arm64→aarch64, arm→arm32
• OS: darwin→macosx, win32→windows, linux→linux
