🗃️ Include review metadata

[shnizzedy]

[W]e want to include a timestamp from when the review was completed and some record of who completed the review. These can be separate PRs, especially since I don't think we ever decided how we want to authenticate / credit reviewers.

The data structure used in https://github.com/nmind/proceedings has deviated a bit from the new schema. I wrote a script to migrate the new format, but the following fields do not currently have an equivalent in the checklist schema:

field	type	clarification
description	string	tool description
image	string	path to tool logo/icon (could be a URL)
toolVersion	string	tool version
date	string	date of review
maintainers	obj[]	array of name+email+affiliation of tool maintainers
evaluatorEmail	string	email address of evaluator
