[Sponsors page] Display recent but not current Sponsors
Feature Request
Description
The list of sponsors at https://scipost.org/sponsors/ shows all organizations which have an ongoing subsidy. It would be useful to include a list of "Recent sponsors" at the bottom of the page where we list organizations that had a subsidy that expired within the last year and have no ongoing subsidy.
