Chore(docs): Add references to the fern-ui and fern-reporter projects

[anoop2811]

Add references to the fern-ui and fern-ginkgo-client projects in the README.md so that people understand the projects in the ecosystem as well as know what these individual projects are for

Perhaps as a "See Also" section

We also probably need a simple arch diagram that shows the different projects and their interactions

[anoop2811]

Essentially the flow is :

fern-ginkgo-client --(json)---> fern reporter --(graphql)---> fern-ui
|-----(go templates)--------> embedded html report

[anoop2811]

We also need to add the compatible versions for each of these projects in this README

[mbristol580]

do we want to add references to the fern-junit-client as well ?
