fix(examples): use hardware I2C (not SoftI2C) in smart-ui-eyes

OSError: [Errno 19] ENODEV at ssd1306.SSD1306_I2C(...) on
100d-esp32-oled-smart-ui-eyes-animation-time-and-weather-micropython.

MicroPython SoftI2C bit-bangs GPIO directly. Velxio's ESP32 QEMU
bridge listens on the emulated I2C peripheral (registers slaves like
0x3C wokwi-ssd1306 against it) and doesn't decode bit-banged GPIO
toggles as I2C frames, so the OLED never sees any writes and
i2c.writeto() returns ENODEV on first use.

machine.I2C(0, ...) routes through the hardware I2C peripheral that
QEMU emulates, the registered slave receives the bytes, the OLED
panel updates. Same code path the other working SSD1306 MicroPython
examples on this repo already use.

API surface is identical to SoftI2C — only the constructor differs —
so the rest of the user sketch needs zero changes.
