chain-admin: add brand name of Hyperweb

[Anmol1696]

Overview

Since the chain template is of Hyperweb, maybe it would make sense to add brand logo and information of Hyperweb.

We can also change the links to:

• github to hyperweb-io repo and website link to hyerwepb.io.
• twitter to hyperweb twitter.

For now we can keep the link to discord and youtube the same.
