URL: https://github.com/apache/datafusion/pull/11691

   ## Which issue does this PR close?
   
   N/A
   
   
   
   ## Rationale for this change
   
   Now that arrow/parquet 52.2.0 is released 
https://github.com/apache/arrow-rs/issues/5998 let's use it
   
   The main rationale for upgrading is that this has several additional 
performance improvements related to StringView that @XiangpengHao  and @a10y 
have been working on. It will unblock merging in the string-view2 branch: 
https://github.com/apache/datafusion/pull/11667

   <!--
   We typically require tests for all PRs in order to:
   1. Prevent the code from being accidentally broken by subsequent changes
   3. Serve as another way to document the expected behavior of the code
   
   If tests are not included in your PR, please explain why (for example, are 
they covered by existing tests)?

   ## Are there any user-facing changes?

   If there are user-facing changes then we may require documentation to be 
updated before approving the PR.
