Add a role and remove another in one reaction role | Carl-bot Swap Method

This is the prefix version of commands, they're NOT outdated. Carl-bot has the message intents. Read the explanation below.

As of August 31st 2022, slash commands are a discord requirement due to the message content intent becoming privileged. Which means developers now need to apply for the intent, Carl has this intent and if it were to change then there would be an announcement made in Carl-bot Help, the official Carl-bot support server where you'll be kept up to date with changes to the bot and any important updates.
