Move Kogito Serverless Workflow guides to the temporary DP1 docs repo

This EPIC is to track the tasks to bring the Kogito Serverless Workflow guides to a specific OpenShift Serverless repository.

The outcome is:

• All the guides for DP1 migrated from https://github.com/kiegroup/kogito-docs/tree/main/serverlessworkflow/modules/ROOT/pages to https://github.com/openshift-knative/docs
• Have the OpenShift Serverless product look and feel
• Add a page to describe the product
• Add a page to describe how customers should configure their application to use the productized binaries

To accomplish this, we need:

• Restructure a few pages upstream to remove the "Kogito" wording. It should be replaced by "OpenShift Serverless Logic" instead via variables
• Migrate the Asciidoc pages from Kogito Docs as is
• Configure the YAML files to have the correct variables in place
• Do the needed configuration to update the live website
