Thanks for the heads up, I didn't realize. I just removed it, I don't think it adds much value to say we're writing to the file here. But let me know if you've got a better idea.

Which issue does this PR close?
None
Rationale for this change
The example in https://docs.rs/parquet/latest/parquet/arrow/index.html#example-of-reading-parquet-file-into-arrow-record-batch is using a deprecated API.
What changes are included in this PR?
A different example using the recommended API. The example is simpler than the original one, but I don't fully understand what the original example was trying to show. Feedback on how to extend/improve the example I wrote very welcome.
Are there any user-facing changes?
Only to the docs
