GH-45587: [C++][Docs] Fix the statistics schema link in `arrow::Recor…

…dBatch::MakeStatisticsArray()`'s docstring (#45588)

### Rationale for this change

`arrow::RecordBatch::MakeStatisticsArray()`'s docstring uses https://arrow.apache.org/docs/format/CDataInterfaceStatistics.html not https://arrow.apache.org/docs/format/StatisticsSchema.html for statistics schema URL.

Because #44252 assumed that we use #43553 but we use #45058 finally.

### What changes are included in this PR?

Fix URL.

### Are these changes tested?
It does not need since just a correction in document

### Are there any user-facing changes?
No, Just a correction in document
