dist: Support Liberica NIK (#878) (#1112)

Add the `liberica-nik` distribution (Liberica Native Image Kit), a
GraalVM-based build from BELL Software resolved via the Bell-SW
`/v1/nik/releases` API.

- `java-version` matches the embedded JDK version (from the release's
  `liberica` component), consistent with every other distribution.
- `java-package: jdk` installs the `standard` bundle; `jdk+fx` installs
  the `full` bundle with JavaFX/Swing support.
- Supported on Linux, macOS and Windows for x64 and aarch64.

+### Liberica Native Image Kit
+Liberica Native Image Kit (NIK) is a GraalVM-based distribution. `java-version` selects the underlying JDK version (e.g. `17`, `21`, `25`). Use `java-package: jdk+fx` to get the `full` bundle with JavaFX/Swing support; otherwise the `standard` bundle (with extra languages) is installed. Available on Linux, macOS and Windows for `x64` and `aarch64`.
