boards: stm32: Fix User LD1 pin assignment

[levietduc0712]

The green LED (User LD1) on the NUCLEO-H755ZI-Q board was previously configured
to use pin PA5 in the Device Tree source file (nucleo_h755zi_q.dtsi).

However, according to the board's user manual (UM2408), User LD1 can be connected
to either PA5 or PB0 depending on the solder bridge configuration:

• PB0: SB65 OFF, SB54 ON (default configuration)
• PA5: SB65 ON, SB54 OFF

Since PB0 is the default configuration on most boards out of the box, this patch
updates the green_led node to use pin PB0 (&gpiob 0) instead of PA5.
