[JonLiu1993]

Fix CI baseline:

REGRESSION: mongo-c-driver:x64-linux failed with BUILD_FAILED.

CMake Error at build/cmake/LoadVersion.cmake:9 (string):
  string sub-command REGEX, mode MATCHALL needs at least 5 arguments total to
  command.
Call Stack (most recent call first):
  CMakeLists.txt:20 (LoadVersion) 

This issue was introduced by #34994, reference PR #35276.

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.
