Nonexistent `docker desktop` subcommands exit 0

Comienza reproduciendo docker desktop nonexistentcommand y comparando su estado con el estado de salida distinto de cero esperado. El payload no menciona archivos ni pruebas, así que sigue el punto de entrada del plugin CLI de docker desktop y añade cobertura de regresión que demuestre que los subcomandos desconocidos fallan sin un indicador de ayuda. Se considera terminado cuando el comando ya no permite que se ejecute el echo encadenado.

Description

Running a nonexistent docker desktop subcommand exits successfully. This makes it difficult to feature test the docker desktop command.

docker desktop nonexistentcommand && echo nonexistentcommand succeeded

It's arguable if this should be the behavior with ``docker desktop nonexistentcommand --helpbut it definitely feels off when a help flag isn't present. I am specifically thinking about putting adocker desktop update` command in my dotfiles, but I'm not sure how to test for the command's existence in the currently installed version of docker.

Apologies if this is more an issue for docker/for-mac, happy to move it if so.

Reproduce

docker desktop nonexistentcommand && echo nonexistentcommand succeeded

Expected behavior

Nothing will be echoed and docker will exit with a non-zero status.
