Update templates for hardware model v2

Updated the board templates for "zmk keyboard new" to support Zephyr's
hardware model v2. Also updated links to Zephyr's documentation to point
to Zephyr 4.1 to match the ZMK update that brings in hardware model v2.

 If ZMK doesn't support your keyboard yet, you can run `zmk keyboard new` to create a new keyboard from a template.
 
-This won't walk you through all of the details of adding support for a new keyboard, but it will generate most of the boilerplate for you. See the [New Keyboard Shield](https://zmk.dev/docs/development/hardware-integration/new-shield) guide for how to finish writing the keyboard files.
+Note that this will generate most of the boilerplate for you, but you will still need to manually edit the files to match your keyboard. See the [New Keyboard Shield](https://zmk.dev/docs/development/hardware-integration/new-shield) guide for how to finish writing the keyboard files.
