Feature request: generation of refreshToken via wpcli

[gilzow]

I have a system that brings up a clone of my WordPress instance (running wpgraphql and this plugin) in a dev environment, alongside a development instance of my nextjs app. Because of the timing, I need to generate the refreshToken before the wp server is available publicly (I need to write the token value to the .env file being injected into the nextjs container). It would be exceptionally handy to have a wp-cli command for generating the token so I could attach it to the pre-deploy hook.

I've written the code to do so as a separate plugin, but am wondering if you'd be interested in a PR to add it officially?
