[Documentation]: Update examples page

[aliabbasjaffri]

Describe the documentation change

Currently the documentation hosted on mlinfra.io is rather plain and bland, especially the examples section. The example section needs to be updated to be more engaging and gives a wider perspective of the utility of the tool.

Importance of the change

The examples section needs to be updated in a way that it provides user with much better experience of what the example does and how can they possibly build stack of their own and run it using mlinfra
