Kiota plugin should not generate function for API with request body contains nested object

[SLdragon]

What are you generating using Kiota, clients or plugins?

Kiota plugin

In what context or format are you using Kiota?

Windows executable

Client library/SDK language

None

Describe the bug

From API plugin schema document, Function parameters should not contains nested object: https://spec-hub.azurewebsites.net/specifications/PluginManifest-2.1.html#type-0

So when generate API plugin file, Kiota should remove these APIs.

Example yaml file that contains nested object in request body:
