Add option to configure Parquet DataPage version when writing

[hcrosse]

Feature Request / Improvement

GetWriteProperties() hardcodes parquet.WithDataPageVersion(parquet.DataPageV2) with no way to override it. This causes issues with consumers that don't fully support DataPage V2 (e.g. Snowflake).

iceberg-java supports configuring this via WriteBuilder.writerVersion(), but iceberg-go has no equivalent.

I checked a few Iceberg library implementations, and iceberg-go is the only one I found that defaults to DataPage V2:

• iceberg-java hardcodes WriterVersion.PARQUET_1_0 which produces V1 pages
• pyiceberg doesn't set data_page_version, so PyArrow defaults to V1
• iceberg-rust doesn't set it, so arrow-rs defaults to V1

I propose that we add a way to configure DataPage version, similar to iceberg-java's WriteBuilder.writerVersion(). I think we should still keep the current default (V2) for backward compatibility.

I'm happy to discuss the best place to expose this in the API and to submit a PR for this if the approach is approved!
