Update images in xcNFT.md

[dudo50]

Project Abstract

Dear Web3Foundation team,

Following a recent update to amend the wallet address, the images in the proposal appear to have stopped displaying properly. I have since re-uploaded them to resolve the issue. I also quickly went through our other proposals and noticed, that the very first one had broken image links also. I will be opening another PR to address this.

Sorry for this inconvenience!
