"npx create-bolt-uxp" interface does not handle paths properly

[gregbenz]

When running "npx create-bolt-uxp", a few issues arise around the first prompt for the install path:

• Trying to accept the default path (./) shows a "valid is required" warning.
• If you clear it and drag and drop a path such as "/Users/admin/Temp", the project tries to create "/Users/admin/Temp/Users/admin/Temp" (as if you typed the path string twice)
• If you drag and drop the file path to the Terminal, it will not have a trailing slash. That's fine in Terminal, but fails in this case if you don't add the slash after dragging and dropping the folder.
