Reduce default resource limit for disk from 80% to 75%.

After the changes in https://github.com/vespa-engine/vespa/pull/20818,
the transient disk used as part of index fusion is no longer reported to the cluster controller.
Transient disk usage should be covered by the resource headroom on content nodes,
instead of leading to feed blocked due to natural fluctuations.
We must therefore adjust the limit slightly down, to ensure the content nodes have enough headroom.
