[BUG] FreeRTOS/LwIP thread priority range for TCPIP_THREAD_PRIO, DEFAULT_THREAD_PRIO and SLIPIF_THREAD_PRIO in CubeMX wrong

Hello,I think the correct range for TCPIP_THREAD_PRIO, DEFAULT_THREAD_PRIO, SLIPIF_THREAD_PRIO and possible others in CubeMX LWIP configuration should be -3 to +3 and not 0 to 6.And the default value should be lower than 3 (osPriorityRealtime) defini...
