MLX Getting Started Documentation Bugs

### [MLX Deployment with Kubeflow](https://github.com/machine-learning-exchange/mlx/blob/main/docs/mlx-install-with-kubeflow.md):
- [x] Link to Openshift cluster documentation leads nowhere
- [x] The [reference to the latest `kfctl` release](https://github.com/machine-learning-exchange/mlx/blob/main/docs/mlx-install-with-kubeflow.md#install-kfctl) needs to be fixed:
> 1. Download the latest kfctl {{% kf-latest-version %}} release from the [Kubeflow releases page]([https://github.com/kubeflow/kfctl/releases/tag/{{%](https://github.com/kubeflow/kfctl/releases/tag/%7B%7B%) kf-latest-version %}}).
- [x] Add table describing files within [documentation directory](https://github.com/machine-learning-exchange/mlx/tree/main/docs)
