[P1] Switching debug stage to chiseled image removes required shell

This stage is explicitly documented as the image used by Visual Studio “fast mode” debugging, but chiseled images intentionally omit /bin/sh and most diagnostic tooling. Visual Studio’s container debugger starts vsdbg with docker exec … /bin/sh -c …; without a shell the attach sequence fails with “executable file not found”, so debugging the sample in fast mode will break. Consider keeping the full aspnet:9.0 image (or installing a shell) for the development stage while still using chiseled images for production.
