RGB565 value for pink was same as magenta. This is obviously wrong, hence correcting to the "pink" value from the docs.
While I'm far from certain about the "right" shading of color nuances, the correction does "reasonably pink" in my eyes (on a ST7789), and assuming that the value from the docs was sourced from something relevant to the small displays used with Tasmota, I consider the change to be at least a move in the right direction.
Still, the corrected value (FF80C0 in RGB888) does have the name "tea rose" when using HTML color codes as a reference, but "some people" may have more interest in long discussions like what pink "really" is.
