[Fix] support arm64-musl on Alpine Linux

Browse Source 
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.

[Tests] `nvm_get_arch`: expect arm64-musl on Alpine
