Add `HestiaCP` (Admin) extension

[xmok]

Description

This is a Raycast extension for Hestia Control Panel Admin level accounts. With this extension you can manage Users, Domains, Mail Domains, Databases, and more. This is an extension I started in February but only recently got the time to work more on. Thus, there are a LOT of features/endpoints/commands that I have NOT yet incorporated but will in the future as I am running HestiaCP (see last section of README).
