emi20 update (#14013)

* Update keymap & readme

-Keymap.c: Key combinations removed for resetting and added a new way to reset. Also removed unused timer code.

-config.h & rules.mk: Removed on kemap level (these were there for the key combo's)

-Readme.md: Changed the preview image and changed the description to reset the keyboard. Also added what connector type is used.

* Update readme.md

Better wording on how to get the keyboard in bootloader mode

* Update keymap.c

Switched + and - around, same with / and *.
