Change Discord name to in-game nameSuggestion

This one does it and is the only reason I haven't switched everything to Discord Core yet.
We use Discord Auth and Sync for the players and Core and Chat for the crew.
Turned them off and not a single issue since.
DiscordAuth and DiscordSync works fine although I have it set to reload every 30 minutes with TimedExecute, otherwise the extension/Discord bot closes the connection and the bot goes offline.
I have no issues with DiscordCore, and I use DiscordChat so the crew can help the players in game chat without having to log on to the server.
That said, I haven't used DiscordCoreRoles because of the lack of name sync so I cannot attest to the performance/stability of that.
I do like the compartmentalization of MJSU's plugs and we use MagicPanel as well with great success.
