feat(templates): add list-numbers, transfers template

[dsTw5]

this function lists the active numbers on a Twilio account or its subaccounts

this is to copy this function to twilio Labs github, to review it with an engineer and move it to QuickDeploy

• I ran npm test locally and it passed without errors.

It looks like that naming pattern is kabob-case rathe than camelCase. Can we rename the template to use kabob-case, "list-numbers"?
