Suggestion: Removing create-ink-app from README

create-ink-app doesn't work on recent Node.js. Its latest commit is 2 years ago and a PR that resolve the error haven't gotten any response for several months. I suspect create-ink-app instruction in README can be harmful because:

• For beginner, they aren't likely to be able to fix problems in apps created by create-ink-app.
• For experienced developers, setup ink by themselves from scratch are likely to be faster than resolving create-ink-app problems.
