Description

fixes #4026

To cover all requirements, we've switched back to a placeholder value and added a new hint how to install into the current directory.

Testing Instructions

• run pnpm cli
• quit it right away (we just need the file statics in place)
• create a new directory
• cd into it
• run node ../packages/create-qwik/dist/create-qwik.cjs
• add . or ./ when asked for the app directory
• check the new output line where the app will be installed
• install and check the output
• redo all of them but also add at least one file into the new created directory to check the handling there

Checklist:

• My code follows the developer guidelines of this project
• I have performed a self-review of my own code
• I have made corresponding changes to the documentation
• Added new tests to cover the fix / functionality
