Merge #21446: Update vcpkg checkout commit

b9e3f35 Update vcpkg checkout commit. (Aaron Clauson)

Pull request description:

  Previously vcpkg was relying on `https://repo.msys2.org/mingw/i686/mingw-w64-i686-pkg-config-0.29.2-1-any.pkg.tar.xz` which is no longer available. The vcpkg source has been updated to use `http://repo.msys2.org/mingw/i686/mingw-w64-i686-pkg-config-0.29.2-2-any.pkg.tar.zst`.

  This PR updates the commit ID used to checkout vcpkg for the updated URL.
