An-style pin names are not mentioned in the analogRead() reference

https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/

Moved from arduino/Arduino#8043 by @benpaddlejones

The reference has:
Parameters pin: the number of the analog input pin to read from (0 to 5 on most boards, 0 to 7 on the Mini and Nano, 0 to 15 on the Mega)

Should update to include UNO analogRead/analogWrite pins are A0, A1, A2, A3, etc and also link to analogueWrite pwm documentation to prevent confusion.
