`DataScan` `count` method does not respect limit

### Apache Iceberg version

0.9.1 (latest release)

### Please describe the bug 🐞

When calling `count()` on a `DataScan`, limit is not respected. Seems trivial but if I set a limit of 5 I expect 5 or less rows back, at least with a scan-like implementation

The underlying `ArrowScan` does not get passed the limit param

https://github.com/apache/iceberg-python/blob/main/pyiceberg/table/__init__.py#L1940

This results in scans taking longer due to not respecting the limit.

The fix will involve more than just passing the limit to the `ArrowScan`

pyiceberg/table/__init__.py の 1940 行目付近から始め、基盤となる ArrowScan 呼び出しを通じて DataScan.count を追跡します。limit がどのように伝播されるかを確認し、issue の注記が調整の必要性を示している追加のスキャン動作を特定します。count() が要求された limit を超えて返さず、不要なスキャン処理を避けられれば完了です。
