Ensure minimalMode previousCache expire time is capped

[ijjk]

This is a follow-up to #34935 which ensures we don't consider the full revalidation time for how long the previous cache item should be leveraged since a long expire time can prevent on-demand revalidations from being able to update the cache before the revalidate period has ended.
