Correction for STM32WB5MM-DK Board User Manual: PE3 at CN4 is actually PE4

Hi

I just noticed an error in the STM32WB5MM-DK User Manual V5 UM2825:
In “Table 19. ARDUINO® connector pinout” there is the signal PE3 at pin 5 of the CN4 connector.
The EXTI3_IRQHandler of my project and the Board Schematic V2 MB1292-D01 say otherwise: Its actually PE4.

Just letting you know. I was not sure where to input this information and chose to open this thread to have it placed.
Maybe someone else might save some time by finding this.

Best regards
Manuel
