Inconsistent messaging in `--help` output

[RomainMuller]

Describe the bug

When I do finch build --help, the output ends with:

See also 'finch --help' for the global flags such as '--namespace', '--snapshotter', and '--cgroup-manager'.

However running finch --help does not mention the --napespace, --snapshotter and --cgroup-manager options, which is confusing:

Steps to reproduce

$ finch build --help
$ finch --help

Expected behavior

I expect the output of finch --help to mention the elements that the finch build --help output suggests it should contain; or that finch build --help does not point to finch --help for content that is not presented there.

Screenshots or logs

$ finch build --help
Build an image from a Dockerfile. Needs buildkitd to be running.
If Dockerfile is not present and -f is not specified, it will look for Containerfile and build with it.

Usage: finch build [flags] PATH

Flags:
      --build-arg stringArray    Set build-time variables
      --buildkit-host string     BuildKit address [$BUILDKIT_HOST] (default "unix:///run/buildkit/buildkitd.sock")
      --cache-from stringArray   External cache sources (eg. user/app:cache, type=local,src=path/to/dir)
      --cache-to stringArray     Cache export destinations (eg. user/app:cache, type=local,dest=path/to/dir)
  -f, --file string              Name of the Dockerfile
  -h, --help                     help for build
      --iidfile string           Write the image ID to the file
      --label stringArray        Set metadata for an image
      --no-cache                 Do not use cache when building the image
  -o, --output string            Output destination (format: type=local,dest=path)
      --platform strings         Set target platform for build (e.g., "amd64", "arm64")
      --progress string          Set type of progress output (auto, plain, tty). Use plain to show container output (default "auto")
  -q, --quiet                    Suppress the build output and print image ID on success
      --rm                       Remove intermediate containers after a successful build (default true)
      --secret stringArray       Secret file to expose to the build: id=mysecret,src=/local/secret
      --ssh stringArray          SSH agent socket or keys to expose to the build (format: default|<id>[=<socket>|<key>[,<key>]])
  -t, --tag stringArray          Name and optionally a tag in the 'name:tag' format
      --target string            Set the target build stage to build
