Improve string statistics display in datafusion-cli parquet_metadata

[alamb]

Is your feature request related to a problem or challenge?

@Veeupup implemented the great parquet_metadata feature in #8413 ❤️

While playing around with it however, I noticed that the formatting of string statistics was not super easy to interpret as it is formatted something like [72, 101, 108, 108, 111]

For example:

andrewlamb@Andrews-MBP:~/Software/arrow-datafusion$ datafusion-cli -c "select * from parquet_metadata('parquet-testing/data/data_index_bloom_encoding_stats.parquet')";
DataFusion CLI v33.0.0

Describe the solution you'd like

It would be nice if the output was formatted as an actual string for string arrays. For example as duckdb does (showing that [72, 101, 108, 108, 111] as Hello

andrewlamb@Andrews-MBP:~/Software/arrow-datafusion$ duckdb -c "select * from parquet_metadata('parquet-testing/data/data_index_bloom_encoding_stats.parquet')";

I think this would be a good first issue as there is already an existing test framework and the code is there, it just needs to be updated to improve the display
