[Bug] StorageService override doesn't see the onDidChangeValue function

Reproducible in vscode.dev or in VS Code Desktop?

• Not reproducible in vscode.dev or VS Code Desktop

Reproducible in the monaco editor playground?

• Not reproducible in the monaco editor playground

Description

In version 0.41.0 this works. But after upgrade to the latest 0.52.2 it does't.
After some investigation I can see that versions > 0.41.0 gives error in console but not breaking an app and versions > 0.48.0 started to break an app.
It's reproducible in the playground. Try please.

I tried to debug it in the browser and I see that on the error line I have _storageService.onDidChangeValue and it's defined as function, but it still throws an error.

Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `function hello() {
	alert('Hello world!');
}`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "javascript",
	automaticLayout: true,
}, {
      // Note: Overrides inner editor UI configuration
      storageService: {
        get() {},
        getBoolean(key) {
          // Note: This config is to show property description on property selection automatically
          if (key === "expandSuggestionDocs") return true;
          return false;
        },
        remove(){},
        store(){},
        onWillSaveState(){},
        onDidChangeStorage(){},
        onDidChangeValue(){}
      }
    });

Reproduction Steps

Just refresh. Error will be from start.

Actual (Problematic) Behavior

TypeError: _storageService.onDidChangeValue(...) is not a function: undefined

Expected Behavior

No error

Additional Context

I am trying to override storage service to show property description on property selection automatically. This workaround was helpful in the old 0.41.0 version

Start with the Monaco Editor playground and the provided storageService override, then trace where onDidChangeValue is consumed after the editor is created. Done means refreshing the playground with the override no longer throws the reported TypeError in current versions.
