   Closes #4126
   
   # Rationale for this change
   
   - `write.parquet.page-row-limit` was passed as `write_batch_size`, which 
only sets how often pyarrow checks page size, so the per-page row limit never 
applied.
   - It now maps to `max_rows_per_page` (pyarrow >= 23.0.0). On older pyarrow, 
setting it emits a warning.
   
   ## Are these changes tested?
   
   - `test_writes.py` — `page-row-limit` reaches `ParquetWriter` as 
`max_rows_per_page`, and `write_batch_size` is no longer set.
   
   ## Are there any user-facing changes?
   
   - `write.parquet.page-row-limit` now limits rows per data page.
