### Description
<!-- - Describe your changes. -->
Fix Windows Release CI failure : `onnx.lib(checker.obj) : error LNK2001:
unresolved external symbol "public: int __thiscall
google::protobuf::RepeatedField<int>::size(void)const "
(?size@?$RepeatedField@H@protobuf@google@@QBEHXZ)
[D:\a\onnx\onnx\onnx\.setuptools-cmake-build\onnx_cpp2py_export.vcxproj]`
by setting PATH properly. We should use prepend instead of append.

### Motivation and Context

<!-- - If it fixes an open issue, please link to the issue here. -->
Try to fix #5659. Currently Windows
