Small but important regression in STM32F411CE Black Pill variant .h file

[AndrewBCN]

There seems to be a small but important regression in release 2.0.0 vs 1.9.0 in the file
Arduino_Core_STM32/variants/STM32F4xx/F411C(C-E)(U-Y)/variant_BLACKPILL_F411CE.h
lines 114-117
// I2C definitions
#ifndef PIN_WIRE_SDA
#define PIN_WIRE_SDA PB3
#endif

PB3 is incorrect, it should be PB7. In release 1.9.0 it was PB7.

I confirmed this with a STM32F411CEU6 Black Pill I am working on these days, running the "I2C scanner" example.

I am not sure if this is a typo, or if the file is automatically generated from some other files, which would mean the regression is somewhere else.
