docs: add section about interrupts to the quick reference (e.g. for ESP32)
I could not find the information that e.g. all interrupts on the ESP32 are soft interrupts and
the limitations about memory allocation mentioned at https://docs.micropython.org/en/latest/reference/isr_rules.html
are not relevant. This could be added to a section about interrupts in the Quickref.
Some text:
On ESP32 for example, all IRQs are "soft" which means they run in the MicroPython scheduler.
In general, the foo.irq(..., hard=) kwarg lets you control whether an IRQ is hard (runs in true interrupt context, no allocations) or soft (not very many restrictions). http://docs.micropython.org/en/latest/library/machine.Pin.html#machine.Pin.irq On ESP32 this kwarg is ignored because it must always be soft, but for example Pyboard/STM32 lets you use either.

GPIO interrpt pins added for ESP32
@dpgeorge PR for Issue #6581, where I have added the interrupt pins for ESP32.
Also, I want to participate in GSOD but can't seem to contact my mentors thru any IRC Channel or Micropython forum or thru mail. If you know about them, can you please suggest me an alernative
