[SPARK-16530][SQL][TRIVIAL] Wrong Parser Keyword in ALTER TABLE CHANGE COLUMN
#### What changes were proposed in this pull request?
Based on the [Hive SQL syntax](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ChangeColumnName/Type/Position/Comment), the command to change column name/type/position/comment is `ALTER TABLE CHANGE COLUMN`. However, in our .g4 file, it is `ALTER TABLE CHANGE COLUMNS`. Because it is the last optional keyword, it does not take any effect. Thus, I put the issue as a Trivial level.
