How do I create a route with a page callback in Drupal9?

To create a route file with a page callback in Drupal, you can follow these steps:

Create a new file in your module's src/Routing directory, named module_name.routing.yml. In this file, define your route using the YAML syntax. An example of a basic route might look like this:

module_name.example:
 path: '/example'
