Allow uploading a new model version to Google Cloud Vertex AI Model Registry using the `UploadModelOperator`

[GLaDAP]

Description

Using Vertex AI, it is possible to upload a model as a new version of an existing model. This is possible by passing the parent_model to the UploadModelRequest. However, the ModelServiceHook.upload_model (under airflow.providers.google.cloud.hooks.vertex_ai.model_service.py) does not allow a user to pass the parent_model.

Currently, when a new model is uploaded, a new model is created instead of creating a new version on an already existing model.

Use case/motivation

Adding this feature enables users to use the model versioning functionality in Vertex AI.
