### What changes were proposed in this pull request? When skewed join optimization split more skewed readers, the plan may be very large and can not be shown in ui quickly. The config `spark.sql.adaptive.skewedJoinOptimization.skewedPartitionMaxSplits` is to resolve the above ui shown issue. And after [PR#27493](#27493) combined the skewed readers into one, we not need this config. ### Why are the changes needed? remove the unnecessary config ### Does this PR introduce any user-facing change? No ### How was this patch tested? existing test Closes#27673 from JkSelf/removeMaxSplitNum. Authored-by: jiake <ke.a.jia@intel.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit f4696ba) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
