feat(weact_stm32g431_core): Configure VND050AJ driver pins in overlay

Updated the weact_stm32g431_core.overlay to define the GPIO and ADC
pin assignments for the VND050AJ driver. This includes:
- Digital I/O pins (IN0, IN1, RST, S0, S1, SEN) configured as GPIOs.
- Analog input pin (MULTISENSE/PA0) configured for ADC1.
