Pimentoso Paddino02 clean-up (#12263)

* fork rules.mk to be version-specific

* remove pimentoso/paddino02 as a keyboard target

This commit makes it so QMK API doesn't identify pimentoso/paddino02 as a build target on its own, because there's no actionable code here.

* add image to readme.md

* unify rules.mk files to QMK AVR template

- remove Bootloader selection comment block
- sort Build Option rules
- unify inline comments
