[release/2.x] Set Default Parameter for edge in timerAttachInterupt(...) Function

Set Default Parameter for edge in timerAttachInterupt

The actual Documentation for the funtion timerAttachInterupt(...) looks like:

But the actual code look like:

To be consistent with the documentation, and edgeis not supportet:
see:

void timerAttachInterruptFlag(hw_timer_t *timer, void (*fn)(void), bool edge, int intr_alloc_flags){
    if(edge){
        log_w("EDGE timer interrupt is not supported! Setting to LEVEL...");
    }
    timer_isr_callback_add(timer->group, timer->num, timerFnWrapper, fn, intr_alloc_flags);
}

A default parameter for edge = false would be a good change to be consistent with the documentation.

Default values can be given only for C++ functions/methods. In C that is not allowed.

so... the docs you are looking at are for the 3.0.0 version. In 2.x the parameter exists and should exist to not break compatibility.
