[fix](doc) explode-json-array-int-outer.md zh: rewrite (page was a stray copy of the json-outer page)

[boluor]

Summary

Doc page (4.x): `i18n/zh-CN/.../table-functions/explode-json-array-int-outer.md` (ZH).

The ZH page at this path was an exact copy of the `explode-json-array-json-outer` page — frontmatter title, prose, syntax block, parameters, examples — all describing the JSON-outer function instead of the INT-outer function the file path claims. Readers following the function-reference link landed on docs for the wrong function.

This PR replaces the ZH `explode-json-array-int-outer.md` content with a translation of the EN version of the same page, so the page actually describes `explode_json_array_int_outer`.

The `explode-json-array-json-outer` ZH page is untouched — it's already correct.

Verification

```
mysql> CREATE TABLE example(k1 int) properties('replication_num'='1');
mysql> INSERT INTO example VALUES(1);
mysql> select * from example lateral view explode_json_array_int_outer('[4, 5, 5.23, null]') t2 as c;
+------+------+
| k1 | c |
+------+------+
| 1 | 4 |
| 1 | 5 |
| 1 | 5 |
| 1 | NULL |
+------+------+
```

Matches the documented result block.

Test plan

• ZH page now matches EN page structurally (same examples, translated prose).
• Lead example runs on Apache Doris 4.1.1 with the documented output.
• explode-json-array-json-outer ZH page not modified.
