Description of Change
As pointed out by a user, ESP32 and ESP32S2 had their defaut pins changed to avoid issue with PSRAM and Flash (DIO/QIO) pins.
That was done in #8800 for 3.0.0.
But it was also imported as part of #9176 to 2.0.15.
This PR fixes and rolls back those Pin chenges.
26-> 94-> 1827-> 105-> 174-> 1625-> 17Tests scenarios
Just CI.
