config: Config example for a SKR Mini E3 v2.0 (#2929)

This is a basic config example for a SKR Mini E3 v2.0, the pinouts are different than the 1.2 and requires different compile options, so worth having an example.

+# This file contains common pin mappings for the BIGTREETECH SKR mini
+# E3 v2.0. To use this config, the firmware should be compiled for the
+# STM32F103 with a "28KiB bootloader". Also, select "Enable extra
+# low-level configuration options" and configure "GPIO pins to set at
+# micro-controller startup" to "!PA14".
+
+# The "make flash" command does not work on the SKR mini E3. Instead,
+# after running "make", copy the generated "out/klipper.bin" file to a
+# file named "firmware.bin" on an SD card and then restart the SKR
+# mini E3 with that SD card.
+
+# See the example.cfg file for a description of available parameters.
