"aiKey" not allowed

[roblourens]

Why is this flagged? Did something change in the schema?

In https://github.com/microsoft/vscode-node-debug/blob/master/package.json

Because the aiKey is not something for the public extensions.
This is only for internal extensions and thus we do not want to expose it in the package.json
Apart from that @weinand and me decided that we flag all unkown attributes in the debuggers section, more details about that here #75887

Since the json schema does not support a non public attribute that is allowed we have decided to live with these warnings.

Due to that closing as designed.
Suggestions on improvment are welcome.
