oldest_supported_version() click to toggle source

Oldest version we support downgrading to. This is the version that originally ships with the first patch version of each ruby, because we never test each ruby against older rubygems, so we can’t really guarantee it works. Version list can be checked here: stdgems.org/rubygems
