Subject: [PATCH] avoid a startup hang when Rosetta needs to be installed

By default
- MacOS has no Rosetta installed
- Docker Desktop uses virtualization.framework with Rosetta enabled
- on first start, Docker Desktop will trigger the Rosetta install
  flow which requires manual input (a button click)

Avoid this hang by disabling Rosetta in Docker Desktop.
