BUG: pandas.date_range() raises NonExistentTimeError despite nonexistent="shift_forward" when crossing DST boundaries #62602

[khemkaran10]

start = pd.Timestamp("2024-04-26 01:00:00", tz="Africa/Cairo")
end = pd.Timestamp("2024-04-27 00:00:00", tz="Africa/Cairo")
tz = "Africa/Cairo"
freq = "D"

full_range = pd.date_range(
    start=start,
    end=end,
    freq=freq,
    tz=tz,
    nonexistent="shift_forward", 
    ambiguous=True, 
    normalize=True,
)

Before Fix ❌:

NonExistentTimeError: 2024-04-26 00:00:00

After Fix ✅:

DatetimeIndex(['2024-04-26 01:00:00+03:00'], dtype='datetime64[ns, Africa/Cairo]', freq='D')

• Args nonexistent, ambiguous were not propagating in the codebase, which causes the NonExistentTimeError

• closes BUG: pandas.date_range() raises NonExistentTimeError despite nonexistent="shift_forward" when crossing DST boundaries #62602 (Replace xxxx with the GitHub issue number)
