Subject: [PATCH] CI: set an explicit python-version for test-crc32c and
 test-zarr

Both jobs passed `${{ matrix.python-version }}` to setup-python, but
neither matrix defines that key, so they have run on the runner's system
Python since #839. Pin 3.13, restoring the pre-#839 interpreter.

Closes #855.
