Ethernet Bridge Example - wrong spi pin assignment range for esp32-s2

[Sinclair81]

In /esp-homekit-sdk/examples/ethernet_bridge/main/Kconfig.projbuild the range for spi gpio-pins is 0 - 33.
But the esp32-s2 support spi on gpio-pin 35, 36 and 37.
As an example: my board is a FeatherS2 form Unexpected Maker.
spi sck - gpio 36
spi mosi - gpio 35
spi miso - gpio 37

@Sinclair81 thanks for bringing this to notice. We will make this change soon, but you may also file a PR based on this esp-idf example if you want to :)
