Error in gettz for Europe/Paris timezone

[AlenkaF]

It seems that in case of Europe/Paris timezone the object created from a string representation with dateutil.tz.gettz(...) has changed to Europe/Monaco in release 2.9.0 causing a test to fail on Apache Arrow CI:

        ...
        import dateutil.tz
    
        tz = dateutil.tz.UTC
        assert pa.lib.tzinfo_to_string(tz) == 'UTC'
        tz = dateutil.tz.gettz('Europe/Paris')
        print(tz)
>       assert pa.lib.tzinfo_to_string(tz) == 'Europe/Paris'
E       AssertionError: assert 'Europe/Monaco' == 'Europe/Paris'
E         - Europe/Paris
E         + Europe/Monaco
pyarrow\tests\test_types.py:356: AssertionError
---------------------------- Captured stdout call -----------------------------
tzfile('Europe/Monaco')

Note that this only happens on Windows builds (I can't reproduce it locally on MacOS). Versions of relevant packages on the linked CI build are:

• Python 3.10
• pytest 7.4.4
• python-dateutil 2.9.0
• tzdata database downloaded from https://data.iana.org/time-zones/releases/tzdata2021e.tar.gz
