how to build onnxruntime with latest version of onnx

[ZchiPitt]

Describe the issue

we have a need to run bf16 model in ort, while onnx just added support for bf16 for many ops in Opset22 (onnx/onnx@4e7289d)

What is the best way to build the ORT with the latest onnx version? We tried by following https://github.com/microsoft/onnxruntime/blob/main/docs/How_To_Update_ONNX_Dev_Notes.md.

However we are still hitting the errors:
INVALID_GRAPH : Load model from down.onnx failed:This is an invalid model. In Node, ("/block/resnets.0/norm1/Reshape", Reshape, "", -1) : ("sample_in": tensor(bfloat16),"/block/resnets.0/norm1/Constant_output_0": tensor(int64),) -> ("/block/resnets.0/norm1/Reshape_output_0": tensor(bfloat16),) , Error No Op registered for Reshape with domain_version of 22

See what change was added in #19745 for reshape. You need to do something similar for the new opset 22.
