Create service binding guide for main odo.dev site

/area documentation /kind bug

What mistake did you find / what is missing in the documentation?

We have the blog: https://odo.dev/blog/binding-external-service-with-odo-v3/

But there's no "full" example (shows all the devfile.yaml),

We need to create some documentation that follows the similar format to the quickstart on https://odo.dev

What is the relevance of it?
