docs: advance xenia-edge standalone pin to d881a29

101 upstream commits. Japanese glyphs now come from M PLUS 1p embedded with the Inter font (imgui_drawer.cc:481-498), so msgothic.ttc and the fontconfig CJK match are no longer read; XConfig gained a per-title random MAC address. Still no system file read. The libretro core is still at f23c14c.
