SwiftSyntaxBuilder example code failing

I am trying to compile the SwiftSyntaxBuilder example code at GitHub.

For some reasons it is failing for me with following error:

Am I missing anything over here?

I don't face the error on my side doing

git clone --branch swift-DEVELOPMENT-SNAPSHOT-2022-12-21-a https://github.com/apple/swift-syntax
cd swift-syntax/Examples
swift run CodeGenerationUsingSwiftSyntaxBuilder

I only used the tag swift-DEVELOPMENT-SNAPSHOT-2022-12-21-a to talk about a common state of the repository. It should not matter as the examples haven't been touched for quite a while.

Do you still get the error?
