[DOC] Rewrite this DAO uses page into a proper DOCS page or blog entry

[charleslavon]

Is your feature request related to a problem? Please describe. economics.md currently references this old wordpress page: https://pages.near.org/use-cases/dao/ The DAO content on this page should be re-written, perhaps as a blog or a regular docs page, because most of the wordpress content is very out of date and likely to be deprecated.
