Update tutorial(s) in docs

[krisbitney]

Our documentation contains a tutorial for creating wraps https://docs.polywrap.io/tutorials/create-wraps/tutorial/project-setup

The tutorial asks users to clone and modify a wrap located in our deprecated demos repo. It also uses ENS URIs, which we have moved away from in favor of IPFS and Wrapscan URIs.

We should replace the tutorial with a new, updated, simpler one. Instead of modifying an existing wrap, the tutorial should start with npx polywrap create and create a new wrap.
