Add Handbook Section to Community Section

[Ayush9026]

Description:

We need to add a Handbook section to the Community section of our website. The Handbook will contain essential information, guidelines, and resources for community members, including contributors, users, and newcomers. This section is crucial for providing a centralized source of information and improving community engagement.

I'm not sure what this means and if it's needed. We should clarify some before spending time on it.

Alright @mattlord
