Description

When I try to run a buildx command that doesn't exist, it doesn't show any errors about an unknown command, it only shows the help:

; docker buildx asdfasdf

Usage:  docker buildx [OPTIONS] COMMAND

Extended build capabilities with BuildKit

Options:
      --builder string   Override the configured builder instance

Management Commands:
  imagetools  Commands to work on images in registry

Commands:
  bake        Build from a file
  build       Start a build
  create      Create a new builder instance
  du          Disk usage
  inspect     Inspect current builder instance
  ls          List builder instances
  prune       Remove build cache
  rm          Remove a builder instance
  stop        Stop builder instance

Expected behaviour

buildx should tell me that the command doesn't exist

Actual behaviour

buildx only shows the help

Seems err is nil in https://github.com/docker/buildx/blob/1de332530f6c21e69ddf8577fbc7adcf0ae7c723/cmd/buildx/main.go#L88

I'm looking at it
