Which issue does this PR close?

Closes #3476

I've picked up here where @Ted-Jiang left off in #3477. I think that I've dealt with some of the comments.

However, I'm not sure if we also need to check that the maximum value is each row group is greater than or equal to the value in the previous row group? This would involve accessing the row group level statistics.

I'd really appreciate thoughts and advice here as I'm keen to learn more about Datafusion and hopefully be able to contribute more in the future!

Is there any way we can make a test for this functionality? Like do we have any parquet files that have is_sorted set?
