swift help for package-registry doesn't work

[toffaletti]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

Running:

swift package-registry

Gives help output that ends with this:

See 'swift help package-registry <subcommand>' for detailed help.

Trying that ends in failure:

❯ swift help package-registry login
Error: The value 'package-registry' is invalid for '<topic>'
Help:  <topic>  The topic to display help for.
Usage: swift-help [<topic>] [<subtopics> ...] [-show-hidden]
  See 'swift-help --help' for more information.

Expected behavior

I expect to see the help messages for package-registry subcommands.

Actual behavior

I get an error.

Steps to reproduce

1. swift help package-registry login
