Some snapcraft 7.x commands have irrelevant "help" info

[Robert P. J. Day]

Pretty sure this relates to several snapcraft 7.x commands, but "snapcraft pull --help" displays numerous options that clearly have no relevance for the pull step:

$ snapcraft pull --help
Usage:
    snapcraft pull [options] <part-name>

    Download or retrieve artifacts defined for a part. If part names
    are specified only those parts will be pulled, otherwise all parts
    will be pulled.
