Samples: Bluetooth: conn time sync fix

[HaavardRei]

This commit fixes the following:

• Fix a bug in the initialization of init_val in the GPIOTE task used for the LED, where it would always be initialized to NRF_GPIOTE_INITIAL_VALUE_HIGH and not take the dt_flags into account. This made the LED toggle with inverted polarity on platforms where the LEDs are active high.
• Update references to LED numbers in the README to match the actual sample behavior.
