## Description:

This update for libsodium fixes the following issues:

Changes in libsodium:

Update to 1.0.22: (jsc#PED-16206)

  * Post-quantum key encapsulation is now available. ML-KEM768, the NIST-
    standardized lattice-based KEM, is accessible through the
    crypto_kem_mlkem768_*() functions.
  * X-Wing, a hybrid KEM combining ML-KEM768 with X25519 for protection against
    both classical and quantum adversaries, is available through the
    crypto_kem_*() functions. X-Wing is the recommended KEM for most
    applications.
  * SHA-3 hash functions are now available as crypto_hash_sha3256__() and
    crypto_hash_sha3512__(), with both one-shot and streaming APIs.
  * Performance: NEON optimizations for Argon2 on ARM platforms.
  * Performance: SHA3 (Keccak1600) now leverages ARM SHA3 instructions when
    available on ARM platforms.
  * Performance: WebAssembly SIMD implementations of Argon2 have been added.
  * XOF state alignment has been relaxed.
  * crypto_core_keccak1600_state has been added.
  * Export missing crypto_ipcrypt_nd_keygen() helper function.
  * crypto_auth_hmacsha256_init and crypto_auth_hmacsha512_init now accept NULL
    key pointers (with a zero key length), for consistency with other _init
    functions.
  * Fixed compilation with GCC on aarch64 and gcc 4.x.
  * On aarch64, aes256-gcm is now enabled even when not using clang, including
    MSVC.
  * Libsodium can be directly used as a dependency in a Zig project.
