The page's resistive-touch calibration instructions pointed at the web UI Display Setup -> Calibrate flow, which does not apply to this board: its RGB-parallel panel is driven by ArduinoGFX and touch uses a standalone XPT2046 driver (openHASP#1028) that ships pre-calibrated and is configured via TOUCH_XPT2046_* build flags. Correct the note accordingly. Signed-off-by: Luc Van <lucvan@gmail.com>

Follow-up to openHASP#1028, which adds working resistive (XPT2046) touch for the Sunton ESP32-4827S043R.
This page's RESISTIVE setup note told users to calibrate via Display Setup → Calibrate in the web UI. That doesn't apply to this board: its RGB-parallel panel is driven by ArduinoGFX, so touch runs through a standalone XPT2046 driver (its own SPI bus) that ships pre-calibrated and is tuned via
TOUCH_XPT2046_*build flags, not the web-UI Calibrate flow.The note is corrected to reflect that, and links the driver PR for provenance.
Verified on hardware (ESP32-4827S043R): display + calibrated resistive touch working.
