[PR] [fix](doc) v2.1/v3.x: correct ARRAY_ENUMERATE_UNIQ multi-array example result [doris-website]
boluor opened a new pull request, #3859:
URL: https://github.com/apache/doris-website/pull/3859
## Problem
The multi-array example
```sql
select array_enumerate_uniq([1,1,1,1,1],[2,1,2,1,2],[3,1,3,1,3]);
```
is documented as `[1, 1, 2, 1, 3]`, which is **wrong**. `array_enumerate_uniq` returns, for each position, the ordinal of that position's tuple among equal tuples. The by-position tuples here are:
```
(1,2,3) (1,1,1) (1,2,3) (1,1,1) (1,2,3)
```
so the ordinals are `[1, 1, 2, 2, 3]` — the 4th position is the **2nd** occurrence of `(1,1,1)`, not the 1st. The doc had `1` at the 4th position.
## Scope
Present (and fixed) in **v2.1 EN, v3.x EN, v3.x ZH**. Already correct in **v2.1 ZH, v4.x, and dev**, so those are untouched.
This page's other examples are correct (checked by hand and on cluster): the single-array example `[1,2,3,1,2,3] → [1,1,1,2,2,2]` and the description prose `[1,2,1,1,2],[2,1,2,2,1] → [1,1,2,3,2]`.
> Note: this is a "both languages wrong" case on v3.x, so a cross-language diff doesn't reveal it — it was caught by a native v2.1 sweep where v2.1 ZH happened to already be correct.
## Cluster verification (Doris 3.1.4-rc02 and 2.1.11-rc01, identical)
```
mysql> select array_enumerate_uniq([1, 1, 1, 1, 1], [2, 1, 2, 1, 2], [3, 1, 3, 1, 3]);
+-------------------------------------------------------------------------+
| array_enumerate_uniq([1, 1, 1, 1, 1], [2, 1, 2, 1, 2], [3, 1, 3, 1, 3]) |
+-------------------------------------------------------------------------+
| [1, 1, 2, 2, 3] |
+-------------------------------------------------------------------------+
