Change discord interaction package

[jdenoc]

While it works, there is likely a better package out there for Discord interactions. One such package that would probably work in laravel: https://packagist.org/packages/laravel-notification-channels/discord

Should probably change the github actions notifications too. Here are some alternatives:

• https://github.com/Ilshidur/action-discord
• https://github.com/appleboy/discord-action
• https://github.com/sarisia/actions-status-discord
