Describe your use case and the problem you are facing

The wp network meta command is technically named correctly, but most developers know network meta as network options due to the (add|get|update|delete)_network_option() functions.

When you're trying to remember what command to use for network options WP-CLI isn't very helpful, especially for developers who don't know that network options are technically network meta.

Describe the solution you'd like

• Clarify the description of the wp network meta command so it mentions network options
• When a user types wp network option, show a suggestion for wp network meta (currently there's no suggestion)
