David Pilato cbced948c4 Fix example in logging daily rotate configuration
PR #8464 come with a bug in the example provided.

First, the current log file is not compressed so it should not end with `.gz`.
Second, conversion pattern was removing all the log content but was printing only the log date.
Then, the current log filename was hardcoded to `elasticsearch` instead of the cluster name.
