feat(docs): Update documentation to match new Pro Micro nodes

 - A `Kconfig.shield` that defines the toplevel Kconfig value for the shield, which uses a supplied utility to function to default the value based on the shield list, e.g. `def_bool $(shields_list_contains,clueboard_california)`.
 - A `Kconfig.defconfig` file to set default values for things like `ZMK_KEYBOARD_NAME`
 - A `${shield_name}.overlay` file, which is a devicetree overlay file, that includes:
-  - A [chosen](https://docs.zephyrproject.org/2.5.0/guides/dts/intro.html#aliases-and-chosen-nodes) node named `zmk,kscan` which references the configured KSCAN driver (usually a GPIO matrix). For these keyboards, to be compatible with any Pro Micro compatible boards, the KSCAN configuration should reference the [nexus node](https://docs.zephyrproject.org/2.5.0/guides/porting/shields.html#gpio-nexus-nodes) that ZMK has standardized on. In particular, the `&pro_micro_a` and `&pro_micro_d` aliases can be used to reference the standard `A#` and `D#` pins in shields.

   - (Optional) A [chosen](https://docs.zephyrproject.org/2.5.0/guides/dts/intro.html#aliases-and-chosen-nodes) node named `zmk,matrix_transform` that defines the mapping from KSCAN row/column values to the logical key position for the keyboard.
 - A `keymap/keymap.overlay` file that includes the default keymap for that keyboard. Users will be able to override this keymap in their user configs.
