Add CLI support for listing notebook versions

Currently it is difficult to determine available notebook versions through the CLI.

The CLI supports submitting notebook outputs using:

```
-k
-v
```

However, there appears to be no API endpoint to retrieve notebook version history or determine the latest version programmatically.

For automation workflows, it would be useful to have a command such as:

```
kaggle kernels versions
```

that lists notebook versions and their statuses.

Exposing notebook version metadata would enable:
- automation pipelines
- notebook-based competition submissions
- latest-version submission helpers
- tracking notebook execution history

Example output:

```
Version 1 COMPLETE
Version 2 COMPLETE
Version 3 RUNNING
```

Start by tracing the existing CLI handling for `-k ` and `-v ` and checking how notebook metadata is exposed. Define the `kaggle kernels versions ` command and its version/status output, then verify that it supports the automation workflows described in the issue.
