Accepting request 1185062 from devel:languages:python

- Use tarball from GitHub instead of the Zip archive from PyPI,
  the latter has very messy combination of CRLF and LF EOLs,
  which are hard to patch.
- Refresh all patches from the original locations.
- Add CVE-2024-39705-disable-download.patch to make a crude
  workaround around CVE-2024-39705 (gh#nltk/nltk#3266,
  bsc#1227174).
