fix(pkg/storage): If storage.Create fails to clean up recent release versions, return an error

Previously, storage.Create was ignoring the error. This meant that a user that
relied on the recent release version cleanup would not be notified if that
cleanup failed, and release versions could grow without bound.

Closes #9145
