gh-137589: Close file objects in test_zipfile/test_core.py

• Issue: zipfile tests: some files are left opened #137589

Hello, thanks however a PR was already opened for both files yesterday, #138080.

But there are still some file objects that have not been closed in that PR.

You are closing files that should not be opened, if they are opened the test is broken anyway as the error (with assertRaises(error):) is not raised. For some other cases, when a zipfile is opened in a width block, e.g. with zipfile.ZipFile(...) as zf: it is automatically closed, you can think of it as there being an automatic finally: zf.close().

I see, thanks.
