Feature Request for Azure CLI: Support for Azure Cosmos DB for MongoDB (vCore)

**Problem Statement**
Currently, the Azure CLI only supports commands for "Azure Cosmos DB accounts" (such as `az cosmosdb mongodb database create -a my-account -g my-rg -n some-db-name`). However, when attempting to use the same commands for **Azure Cosmos DB for MongoDB (vCore)** clusters, I receive the following error:
```
cli.azure.cli.core.azclierror: (ResourceNotFound)
```

**Additional Information**
- I have **admin permissions** for the resource.
- The **cluster exists** and is correctly configured.
- I am in the **correct subscription**.

Despite these factors, the CLI commands do not work for a **MongoDB vCore cluster**, which limits my ability to automate tasks like database creation and document uploads in a CI/CD pipeline.

**Requested Solution**
It would be incredibly useful to extend the CLI to support the following actions for **Azure Cosmos DB for MongoDB (vCore)** clusters:
- Create databases
- Delete databases
- List databases
- Upload documents
- Other MongoDB-related management tasks

By adding support for these commands, it would enable seamless integration with Azure DevOps or other automation pipelines that require database management functionality.

**Considered Alternatives**
While it is possible to use `mongosh` to manually create databases and documents, this is not practical for a **CI/CD pipeline**, especially one where the pipeline itself does not have direct access to the database, but only to the resource in the Azure portal.

---

**Context for the Request**
I’m currently working on a pipeline that interacts with the resource in the portal, but the lack of CLI support for MongoDB (vCore) is a roadblock. Without the ability to automate tasks such as database creation, it becomes much harder to integrate MongoDB operations within our existing infrastructure.
