[GR-57252] Improve error message when trying to build static image on unsupported platforms

[fniephaus]

Currently, the error message on Linux AArch64 (on which static linking is not supported) looks like this:

[1/8] Initializing... (0.0s @ 0.08GB)
Error: Building images for org.graalvm.nativeimage.Platform$LINUX_AARCH64 (target libc: musl) requires static JDK libraries.
Use most recent JDK from https://github.com/graalvm/labs-openjdk-*/releases
Missing libraries: java, nio, net, zip
(search path: /home/github/actions-runner/_work/_tool/graalvm-jdk-17_linux-aarch64_bin/17.0.0/arm64/graalvm-jdk-17.0.12+8.1/lib/static/linux-aarch64/musl) 

The reference to LabsJDK can be confusing to users as it may suggest you can build on the platform with a different JDK. Instead, the error message should clearly state that static linking is not supported on this platform.
