Visual Studio Code showing error: Property Stages is not allowed, Property parameters is not allowed

Question

I created reusable templates from Azure DevOps yaml pipeline. The build.yaml you see below is one such template.

When I push code, the pipeline successfully runs on Azure DevOps without complaining. However Visual Studio Code complains as I hover on parameters or stages.

Property Stages is not allowed 
Property parameters is not allowed

Am I missing any settings here? Why VS Code shows errors while azure devops runs the same successfully?

And interestingly, I have another template in the same directory, which does not show any such error messages. What am I missing? I restarted vs code, still same.

I observed this problem with both Visual Studio Code as well as Visual Studio 2022 Preview.

This lead me to think, I renamed the file build.yaml to build-stage.yaml. This fixed the issue finally. May be build is some keyword kind of thing internally.
