Reran the existing `Build` workflow on the current head. No code changes
here. The previous GitHub Build failure was again in unrelated shared test
lanes (`TestZKDelegationTokenSecretManager` / `TestHttpServer` in `common` and
`TestDSWithMultipleNodeManager` in the `hdfs-rbf` shard), so this is just a CI
refresh.

> The tolerance percent specifies when we have reached a good enough value for
> any copy step. For example, if you specify 10% then getting close to 10% of
> the target value is good enough.{code}
> Currently, only *{{maxDiskErrors}}* and *{{bandwidth}}* are passed in the
> plan, and it is expected that *{{tolerancePercentage}}* can also be
> propagated to the DataNode.
