Setup Script Fixes

[nbriz]

couple issues with the [setup script](https://github.com/netizenorg/netnet.studio/blob/main/my_modules/setup-script.js

• netnet's ASCII speech bubble doesn't look right on the Windows terminal.

• when netnet prompts users to create a "token" to easily push/pull from ur origin (forked repo) we should make clear that they should check the "repo" permissions in GitHub's page for generating tokens (we might also want to document this in the setup docs)
