Remove usage of datetime_safe

[lociii]

django.utils.datetime_safe has been deprecated and will be removed in DJango 5.0

DJango source code described it's purpose as following:

# These classes override date and datetime to ensure that strftime('%Y')
# returns four digits (with leading zeros) on years < 1000.
# https://bugs.python.org/issue13305
#
# Based on code submitted to comp.lang.python by Andrew Dalke
#
# >>> datetime_safe.date(10, 8, 2).strftime("%Y/%m/%d was a %A")
# '0010/08/02 was a Monday'

This may break for actions dated before the year 1000.
If a removal without replacement is accepted, I would go ahead and provide a pull request.

anything throwing deprecation warnings for future django releases should be fine. please go ahead and make a PR

i dont think a lot of folks are using this app to track actions from the roman empire but it should b removed anyway

After some investigation, this seems like a packaging/release issue.

You already removed the datetime_safe calls in March 2022 in df4b569 and they are not found anymore in the main branch but the current package 1.4.2 still contains them in e.g. actstream/feed.py:10

from django.utils import datetime_safe

Package has been downloaded from GitHub and PyPI both containing the outdated imports and usages.
