Description
The datasheet/pinout for the Nano Every shows A4/A5 as PA2/PA3, but from my reading of the ATMega4809 datasheet, these are not the I2C port that will also support the ADC. The code in pins_arduino.h suggests these are actually PF2/PF3 which does support both I2C and AIN12/13.
Similarly, for the Wifi Rev 2, A4/A5 are listed as PD4/PD5 (18/19) but the SDA/SCL additional pins are also listed as (18/19) but on PA2/PA3.
Is this correct?

Research direction
Start by comparing pins_arduino.h with the ATmega4809 datasheet for the Nano Every and Wifi Rev 2 mappings. Check the A4/A5, SDA, and SCL entries and determine whether the documented ports and ADC/I2C capabilities agree. Done means the mappings are verified and any incorrect datasheet or pinout entries are corrected or clearly explained.
