Fix datasets/cmuarctic test failures when using python 3.13

[pearu]

As in the title.

Previously, cmuarctic tests fail when using Python 3.13:

$ pytest -sv test/torchaudio_unittest/datasets/cmuarctic_test.py
<snip>
        with open(self._text, "r") as text:
>           walker = csv.reader(text, delimiter="\n")
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
E           ValueError: bad delimiter value
E           
E           To execute this test, run the following from the base repo dir:
E               python test/torchaudio_unittest/datasets/cmuarctic_test.py TestCMUARCTIC.test_cmuarctic_str
E           
E           This message can be suppressed by setting PYTORCH_PRINT_REPRO_ON_FAILURE=0

src/torchaudio/datasets/cmuarctic.py:131: ValueError

Note: the same issue is fixed in #3923 by avoiding csv.reader.

Thanks @pearu , before merging can you make sure this still works as expected on 3.10?

Confirming that the cmuarctic test passes on Python 3.10 as well.
