Updated wCCD tutorial

[dragosgd]

Purpose

Improve the wCCD tutorial.

Changes

• Removed unnecessary wallet tutorial and replaced with a reference, images were not deleted, only references to them, they will be deleted after new screenshots are made with the new wallet UI
• Formatted commands for better readability, by adding a space after "$" and removing "./", which is not necessary, as concordium-client should be added to the PATH
• Replaced wrong 8080 port with 4173, as that's the port the app will run on because of Vite
• Removed the link to proxy-implementation-upgradable wccd as that is a closed pull request, it was replaced by natively-upgradable wccd
• Added 2 more references to CIS-2 implementation examples, these being cis2 dynamic-nft and
  cis2 multi-royalties
