What was the end-user or developer problem that led to this PR?
bundle update --bundler
is also suffering from the issue of not being able to tell if the latest bundler supports the current ruby or not :(What is your fix for the problem, implemented in this PR?
My fix is to add the proper filtering so that the correct version is selected, however, that can't be magically propagated to the Bundler version users on old rubies are running, so the issue will keep showing up for users of old rubies that for some reason what to upgrade Bundler.
I didn't write tests because they are tricky due to the implementation hardcoding

. Once #5498 is fixed, it would become easier.Fixes #7308.
