RFC/Feature: Support for vm image technical configuration modifications

I'd like to use this extension for managing the technical configuration for virtual machine images. I've put together a [small POC](https://github.com/Azure/partnercenter-cli-extension/pull/242) that works for adding and removing vm image versions from existing technical configurations. I have read through the docs in the repo and looked for examples. The closets I found was the CNAB bundles. It appears the CNAB code is generated via pydantic. I did take a look at some of the pydantic generated code for the json schema matching the resources I want to update but I ended up with a large number of classes named similar to: `ComSchemaVirtualMachineOpenPort20220301Preview2` and `Field20220301Preview2Model4` So I figured I'd post what I have and see if there's any interest in this functionality or guidance you could provide for generating the python code with less manual transformation needed.
