ZeroDivisionError in BaseSensorOperator with exponential_backoff=True and poke_interval=1

[AVMusorin]

Apache Airflow version

2.6.1

What happened

Sensor is fired with an exception ZeroDivisionError, if set up mode="reschedule", exponential_backoff=True and poke_interval=1

ERROR - Task failed with exception
Traceback (most recent call last):
  File "/home/airflow/.local/lib/python3.9/site-packages/airflow/sensors/base.py", line 244, in execute
    next_poke_interval = self._get_next_poke_interval(started_at, run_duration, try_number)
  File "/home/airflow/.local/lib/python3.9/site-packages/airflow/sensors/base.py", line 274, in _get_next_poke_interval
    modded_hash = min_backoff + run_hash % min_backoff
ZeroDivisionError: integer division or modulo by zero

What you think should happen instead

Throw an human-readable exception about corner values for poke_interval or allow to set up this value less then 2 (if it's >= 2 - rescheduling works fine.)

How to reproduce

from airflow.sensors.base import BaseSensorOperator
from airflow import DAG
import datetime

class TestSensor(BaseSensorOperator):
    def poke(self, context):
        return False

with DAG("test_dag", start_date=datetime.datetime.today(), schedule=None):
    sensor = TestSensor(task_id="sensor", mode="reschedule", poke_interval=1, exponential_backoff=True, max_wait=5)
