tests: update wycheproof files

CHANGELOG.md

@@ -115,7 +115,7 @@ We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to
  - Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14.
 
 #### Added
-  - Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases.

 #### Changed
  - Increased minimum required CMake version to 3.13. CMake builds remain experimental.
