`DefaultEventLoopPolicy.get_event_loop()` is deprecated (in the case of no loop) about falcon

[CaselIT]

seems that what they want you to do for #reasons is the following

try:
  loop = asyncio.get_running_loop()
except RuntimeError: # lol custom exception are for noobs
  loop = asyncio.new_event_loop()
  asyncio.set_event_loop(loop)

I have no idea how someone looked at this and thought "yeah that's a great api to replace get_event_loop" -.-'

nope that's too simple. the following seems correct

def get_event_loop() -> asyncio.AbstractEventLoop:
    try:
        return asyncio.get_running_loop()
    except RuntimeError:
        # avoid "During handling of the above exception, another exception..."
        pass
    if sys.version_info < (3,12):
        return asyncio.get_event_loop()
    else:
        with warnings.catch_warnings(action='error'):
            loop = None
            try:
                loop = asyncio.get_event_loop()
            except (DeprecationWarning, RuntimeError):
                # avoid "During handling of the above exception,
                # another exception..."
                pass
            if loop is None:
                loop = asyncio.new_event_loop()
                asyncio.set_event_loop(loop)
            return loop
