PR Summary

• Added New Authentication Resource Commands
  We have introduced new commands !auth and !authentication. These commands provide responses with useful information about prevalent backend and meta-frameworks for authentication. This includes resources, libraries, and authentication-as-a-service options. Importantly, this information is sent directly to the channel in the form of an embedded message for easy access and understanding. The embedded message is customized to include the description, resources, libraries, and authentication-as-a-service options. Additionally, it adds a personal touch by including a mention of the first user referenced in the message, if any.
