chore(release) ensure release artifacts names include channel

Binary release artifacts of nightly/prereleases such as:

    wasmx-[ver]-v8-[arch]-[dist].tar.gz

Should instead be created with the format:

    wasmx-[channel]-[ver]-v8-[arch]-[dist].tar.gz

E.g:

    Nightly:    wasmx-nightly-1234-v8-[...].tar.gz
    Prerelease: wasmx-prerelease-0.2.0-v8-[...].tar.gz
    Release:    wasmx-1.0.0-v8-[...].tar.gz
