Update the docs for connecting to MLflow via Kubeflow

[kimwnasptd]

Context

Follow up from #244

The recommended way for deploying MLflow and Kubeflow should be with these 2 extra commands:

juju relate mlflow-server:ingress istio-pilot:ingress
juju relate mlflow-server:dashboard-links kubeflow-dashboard:links

And then MLflow should be accessible by clicking on the MLflow row in the CentralDashboard, which will redirect users to a new tab with MLflow (behind Dex).

What needs to get done

We'll need to update the documentation to reflect

1. the above code changes
2. how a user should access MLflow, when exposed with Kubeflow

Definition of Done

1. The current tutorial exposes the two new commands for integrating MLflow with Istio and the Dashboard
2. The above tutorial tells users how to connect to MLflow, when deployed with Kubeflow

@kimwnasptd - Is there any dependency with respect to juju and kf version for running below commands

juju relate mlflow-server:ingress istio-pilot:ingress
juju relate mlflow-server:dashboard-links kubeflow-dashboard:links

I tried above commands with juju: 2.4 and kf:1.7 and it failed

$ juju relate mlflow-server:ingress istio-pilot:ingress
$ juju relate mlflow-server:dashboard-links kubeflow-dashboard:links
ERROR application "kubeflow-dashboard" has no "links" relation

Works with Juju 3.4 and CKF 1.8

One addon question will be currently I am running below commands to enable resource dispatcher to link mlflow with kubeflow. Do I still need to run these commands ?

juju deploy resource-dispatcher --channel 1.0/stable --trust
juju relate mlflow-server:secrets resource-dispatcher:secrets
juju relate mlflow-server:pod-defaults resource-dispatcher:pod-defaults
