### What changes were proposed in this pull request? https://github.com/apache/spark/pull/27507 implements `regexp_extract_all` and added the scala function version of it. According https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L41-L59, it seems good for remove the scala function version. Although I think is regexp_extract_all is very useful, if we just reference the description. ### Why are the changes needed? `regexp_extract_all` is less common. ### Does this PR introduce _any_ user-facing change? 'No'. `regexp_extract_all` was added in Spark 3.1.0 which isn't released yet. ### How was this patch tested? Jenkins test. Closes #31346 from beliefer/SPARK-24884-followup.
