Don't set minimumReleaseAgeExclude unless necessary

Tell us more.

cerbos/cerbos-sdk-javascript#1402 is an example of a security update where the age of the new version is older than the minimum release age, and therefore setting minimumReleaseAgeExclude is unnecessary. It would be good if Renovate avoided cluttering the config if it doesn't have to.
