Panic on datetime column min()

Checks

[X] I have checked that this issue has not already been reported.
[X] I have confirmed this bug exists on the latest version of Polars.

Reproducible example

from datetime import datetime

import polars as pl

df = pl.DataFrame().with_columns(
    pl.datetime_range(datetime(2024, 7, 18), datetime(2024, 7, 19), '15m').alias(
        'datetime'
    )
)

print(df['datetime'].min())

df = df.with_columns(pl.col('datetime').dt.replace_time_zone('UTC'))

print(df['datetime'].min())

Issue description

This appears to happen with other timezones as well, not just UTC. E.g. Europe/London also produced the same error.

Expected behavior

Should not panic and should return a timezone aware datetime like: 2024-07-18 00:00:00+00:00
