`corepack npm` and other package managers are not shown in help text

[rotu]

Calling corepack or corepack --help shows help for e.g. corepack install, but does not suggest the shimless aliases, namely:

• corepack npm, corepack npx
• corepack pnpm, corepack pnpx
• corepack yarn, corepack yarnpkg

These are also not suggested as typo corrections:

corepack np
