Write "What is Keptn?" blog post

[StackScribe]

Summary

I googled for "keptn". First hit is for keptn.sh, second one is to this:

https://www.dynatrace.com/news/blog/what-is-keptn-how-it-works-and-how-to-get-started/

This is really a splendid document, except it is from 2019 and waxes poetic about the product we just killed. It would be nice to have a piece like this for the current Keptn.

DoD

• A well-written blog post that explains what the new Keptn is, how it works, and why it is useful, published as a blog on keptn.sh

I was thinking of writing a blog on Keptn in a few days, after reading about it a bit more. Maybe I can give this a shot 😅
