Configure the project https://openshift-knative.github.io/docs/docs/index.html (https://github.com/openshift-knative/docs) to fetch the Kogito Serverless Workflow guides. Remove the Functions section from the doc.

More specific, what we need is:

1. Bring all the content from Kogito Guides Serverless Workflow to OpenShift Knative repo
2. Change the Navigation to:

Documentation
> Workflows
>> ... (all the content here)

• Documentation should link to the current "Overview" page
• Workflows to the new "About" page hmanwani@redhat.com is writing (see KOGITO-7687) https://docs.google.com/document/d/1q9-EIUUeeqs62AhJxQ3TjAUAYrNCug4yF4RLkzomZmk/edit?usp=sharing

For the navigation at the top, we should remove the "Boson Project" link.
