- Update to 3.9.21:

- Tests
    - gh-125041: Re-enable skipped tests for zlib on the
      s390x architecture: only skip checks of the compressed
      bytes, which can be different between zlib’s software
      implementation and the hardware-accelerated implementation.
    - gh-109396: Fix test_socket.test_hmac_sha1() in FIPS
      mode. Use a longer key: FIPS mode requires at least of at
      least 112 bits. The previous key was only 32 bits. Patch by
      Victor Stinner.
    - gh-100454: Fix SSL tests CI for OpenSSL 3.1+
  - Security
    - gh-126623: Upgrade libexpat to 2.6.4
    - gh-122792: Changed IPv4-mapped ipaddress.IPv6Address to
      consistently use the mapped IPv4 address value for deciding
      properties. Properties which have their behavior fixed are
      is_multicast, is_reserved, is_link_local, is_global, and
      is_unspecified.
  - Library
    - gh-124651: Properly quote template strings in venv
      activation scripts.
    - gh-103848: Add checks to ensure that [ bracketed ] hosts
      found by urllib.parse.urlsplit() are of IPv6 or IPvFuture
      format.
  - Documentation
    - gh-95588: Clarified the conflicting advice given in the ast
      documentation about ast.literal_eval() being “safe” for use
      on untrusted input while at the same time warning that it
      can crash the process. The latter statement is true and is
      deemed unfixable without a large amount of work unsuitable
