nodejs-packaging-bundler: sanitize package name
    
    The NPM package name might contain invalid characters, e.g.
    `@bitwarden/cli`.
    
    Normalize the generated bundles by converting `/` to `-`.
    
    ```
    specs/nodejs on  master
    ❯ ~/src/fedora/pkgs-others/nodejs-packaging/nodejs-packaging-bundler @bitwarden/cli
    ...
