Update content: migrate content from our zenodo lesson in a google doc to our lessons repo

[lwasser]

move the content from the zenodo section of this google doc

https://docs.google.com/document/d/1g4zft2tgkfL-01h8dfcMOv2LwowmiQnDzbUIWHpBxKU/edit?tab=t.0

to a new zenodo tutorial page in this section of our guidebook

https://github.com/pyOpenSci/lessons/blob/main/publish-share-code/

this process will include

1. creating a new file called zenodo.md in that directory
2. adding a link to that lesson in this file so it appears on the landing page of that section
3. adding and expanding upon the content in that zenodo section to flesh out a lesson. The first draft could just be as is in the google doc!
