Bug: open path /0 at uri got error "Class Home does not exist" on development environment

[samsonasik]

When on development environment, open page eg: http://ci4.local/0 got "Class Home does not exist" and when open at production environment it doesn't has error, but show the Home page, I think it should be 404 instead.

CodeIgniter 4 version
4.0.2

Expected behavior, and steps to reproduce if appropriate

On development and production env, it should be 404 page.

Context

• OS: MacOS
• Web server Apache
• PHP version 7.4

also, I can't register route "/0", I think it related with "empty($path)" check in the URI class which 0 is also an empty. It should be compare to empty string instead.
