Hyperdisk Balanced volumes on C4D instances have increased maximum throughput

## Feature Feature Hyperdisk Balanced volumes on C4D instances have increased maximum throughput limits for these machine types: * `c4d-*-96`: 3,125 MiB/s (up from 2,800 MiB/s). * `c4d-*-192`: 6,250 MiB/s (up from 4,800 MiB/s). * `c4d-*-384`: 12,500 MiB/s (up from 10,000 MiB/s).
