Add React Roles

## Overview
Determination of command Group organization needs to be thought about further, but the general idea for this specific feature is that someone with the manage roles permission can use this command to setup react roles for their server.

### Parameters
- `role * 5`
- `channel`

### Things to Consider
- A way to format which roles are with each reaction needs to be determined.
- Permissions and Invite links might need to be updated globally to ensure proper functionality

The issue does not name implementation files, tests, or an entry point. Start by reviewing the command-group organization and existing permission handling, then resolve the reaction-to-role format and determine the required permission and invite-link changes before implementation can be considered done.
