Description of Problem

The v8 completion synopsis was changed (via #4450) to the following (using a generic command template):

npm completion

This is autogenerated using a generic command template, but it is incorrect (at, at the very least, not useful). The v7 page has the right usage, namely:

source <(npm completion)

Potential Solution

Update describeUsage in https://github.com/npm/cli/blob/latest/scripts/config-doc-command.js to treat completion as a special case.
