`atexit` functions are not called when `os.exec*()` is called

[gucci-on-fleek]

Documentation

Running the following test file

#!/usr/bin/env python3
import atexit
import os
import sys

atexit.register(print, "atexit callback called")
# sys.exit()
os.execl("/usr/bin/true", "true")

does not print a message to the console in Python 3.14, but os.exec*() is not included in the list of cases where atexit functions are not called. The atexit module documentation should be updated to also mention os.exec*().
