Original prompt

create a new cog "game_embed"

This cog should monitor a specified game servers. This will only support steam servers that are supported by the python-a2s module (https://github.com/Yepoleb/python-a2s).

The cog should regularly check if the server is online, storing the server name, number of players and the game.

admins or moderators of the discord can then specify to post an embed (that is edited with the latest information) that represents that server. Showing the Server name, the game, the number of players online, and the server ip and port (and any password that might be provided).

Additionally the embed should have a button attached that redirects the user to the steam protocol for immediately joining the game. "steam://connect/:/[password]"

@copilot remove the map "Map: de_dust2" - its not always available

Removed the Map field from the server embed in commit a9b9703. The embed now shows: Status, Game, Players, Address, and Password (if provided).
