[lib: datetime] Updation of a `datetime` object with a `timedelta` obj reflects the change in the `datetime` object but is not reflected in the value returned by the `timetuple()` function

--- MicroPython v1.23.0 on 2024-06-02; Raspberry Pi Pico with RP2040 ---
-- Datetime library installed via mip (mpremote) so: mpremote mip install datetime

Discovery code:

>>> from datetime import datetime, timedelta
>>> from utime import time, localtime, mktime

>>> interval_s = 5 * 60
>>> intervals_passed_in_hr = total_seconds_this_hr // interval_s
>>> next_interval_seconds_in_hr = (intervals_passed_in_hr + 1) * interval_s
>>> seconds_to_next_interval = next_interval_seconds_in_hr - total_seconds_this_hr
>>> next_record_time_dt = now + timedelta(seconds=seconds_to_next_interval)

>>> now
datetime.datetime(2024, 8, 21, 14, 53, 39, 0, None, fold=0)
>>> next_record_time_dt
datetime.datetime(2024, 8, 21, 14, 55, 0, 0, None, fold=0)
>>> next_record_time_dt.timetuple()[:-2]
(2024, 8, 21, 14, 53, 52)
