@PrathamSikka24 many thanks for the PR, unfortunately the commit isn't signed so we can't do anything with it. Please could you sign the commit and repush ?

[PrathamSikka24]

@davidkel Thank you for bringing that to my notice. I've signed and re-pushed the commit. Please review it and let me know if anything else needs to be done.

Rather than storing the image in our repo, we could just reference the one stored in the hyperledger fabric github repo which is
https://raw.githubusercontent.com/hyperledger/fabric/main/docs/source/images/hyperledger_fabric_logo_color.png

Hopefully then we would also pick up the logo change when it occurs.

We can reference the logo directly from the Hyperledger Fabric repo. However, the image in the link has a grey background, unlike our other UI images(logos of Hyperledger Besu, Ethereum), which are transparent. Could we find a transparent version or adapt this one?

For now, I have committed the change as you've suggested. Please let me know in case of anything else.

I have incorporated the necessary suggestion for the image link. I apologize for mistakenly making an extra PR; please don't mind that. Do tell me if anything else needs to be done.
