Explorer "Getting Started" and "Configuration" docs are out of sync and duplicative

Make them consistent, or combine them into one page. Currently, it is just confusing.

@jpellizzari +1. I also see typos like "Weave Gitops" — we should be consistent about formatting our product name correctly. I'm happy to work with you on this or do the initial edit for you to then review. Just ping me later today what you'd prefer.
