fix(pro-dummy): drop --inspect and debug log level from Procfile.dev node-renderer

Align the Procfile.dev `node-renderer:` line with the base `node-renderer`
npm script so it matches the PR description. Previously it was byte-for-byte
identical to `node-renderer:debug`, which carried `--inspect` overhead and
opened port 9229 on every `bin/dev` run. Use `node-renderer:debug` when
debugger access is needed.
