Matrix Cain RE Touch-Up (#20719)

* add matrix_diagram.md

* info.json: apply friendly formatting

* info.json: correct layout data

* info.json: alias LAYOUT to LAYOUT_all

The PCB supports multiple layouts, but I have not been able to discover how the additional layouts are wired.

* update matrix_diagram.md (thanks yulei)

* add LAYOUT_2u_numpad_plus_enter_zero with reference keymap
