Re. SmingHub#2701 call to `timer_ll_trigger_soft_capture` only required for IDF 5.2, as while function signature changed in IDF 5.0 it retains previous behaviour.

In IDF >= 5.0 reading the timer1 counter value always returns 0. This is because the low-level HAL call
timer_ll_get_counter_valuewas changed and requires a separate call totimer_ll_trigger_soft_capture.Timer1 is used for callbacks (
HardwareTimerclass) and this bug doesn't affect that behaviour since it relies only on the alarm functionality.Correction: applies only to IDF >= 5.2 (see #2703)
