Subject: [PATCH] [Fix] support arm64-musl on Alpine Linux

Node.js unofficial-builds publishes linux-arm64-musl binaries since
v20.20.1 / v22.21.1 / v24+. Map NVM_ARCH=arm64 to arm64-musl on
Alpine so `nvm install` resolves to the correct tarball instead of
the glibc-linked arm64 build that won't run against musl.
