Support platform selection in `docker sandbox` command

[hackwaly]

Description

Currently, the docker sandbox command does not support specifying the platform. It would be very helpful to add a command-line option to allow users to select the platform, for example --platform linux/amd64. This feature would enable users on macOS to use Linux/amd64 instead of being forced to use Linux/arm64. Such capability is important for maintaining compatibility with software and environments that expect x86_64 rather than ARM architecture.

Thanks for reporting.

The sandbox command is implemented as a CLI plugin, and the code is not maintained in this repository; unfortunately, the repository for the plugin is closed-sources, so I cannot transfer this ticket, but let me see if I can find someone to look if this would be possible (and where to best report issues with the plugin).
