Replace deprecated BadZipfile with BadZipFile

[hugovk]

BadZipfile (with a small f) has been deprecated since Python 3.2, use BadZipFile (big F) instead, added in 3.2.

• https://docs.python.org/3/library/zipfile.html#zipfile.BadZipfile
• Remove the error and the zipfile.ZipFile.BadZipfile aliases python/cpython#86437
