[Doc] Front page colab notebook refers to "chapter 1" which is inaccessible

[architkulkarni]

Description

If I imagine I'm a new user, the first thing I'm clicking on in the Ray doc landing page is the "Try it out" button:

But the notebook is titled ch_02 and says "In Chapter 1 we showed you how start a local cluster simply by calling import ray and then initializing it with ray.init()." I haven't seen chapter 1 and there's no way to get to chapter 1, which makes me feel like I've done something wrong and maybe I shouldn't be using this notebook. One idea is to remove this reference, or to add a link to Chapter 1.

It's a nitpick, but it affects people's first impressions.

Thanks for filing this issue, @architkulkarni! The link is actually to the wrong notebook. @simran-2797 is working on this PR to update the link: #34924
