Issue on docs runtime-filter code

- Page Link: https://doris.apache.org/zh-CN/docs/query-acceleration/optimization-technology-principle/runtime-filter#%E6%9F%A5%E7%9C%8B-join-runtime-filter

- Version: 2.1

- Reason: 问题1：代码中展示中文句号，应改为英文点；问题2：最好在代码块中加上行号，便于阅读，如下为修改后的代码块；问题3：第5/6行会理解为第5行或者第6行，改为第5和6行更标准

```sql
第1行：OLAP_SCAN_OPERATOR (id=2. nereids_id=351. table name = orders(orders)):(ExecTime: 13.32ms)
第2行： - RuntimeFilters: : RuntimeFilter: (id = 0, type = bloomfilter, need_local_merge: false, is_broadcast: true, build_bf_cardinality: false,
第3行： ...
第4行： - RuntimeFilterInfo:
第5行： - filter id = 0 filtered: 714.761K (714761)
第6行： - filter id = 0 input: 747.862K (747862)
第7行： ...
第8行： - WaitForRuntimeFilter: 6.317ms
第9行： RuntimeFilter: (id = 0, type = bloomfilter):
第10行： - Info: [IsPushDown = true, RuntimeFilterState = READY, HasRemoteTarget = false, HasLocalTarget = true, Ignored = false]
第11行： - RealRuntimeFilterType: bloomfilter
第12行： - BloomFilterSize: 1024
```
