Add multi-row/batch insert for Spark SQL

[gatear]

I was mistaken on the first PR #1261

Spark SQL supports multi-row inserts
https://spark.apache.org/docs/3.0.0-preview/sql-ref-syntax-dml-insert-into.html

Validated on Databricks that the following statement is accepted.

INSERT INTO `MY_TABLE` (`field1`, `field2`)
VALUES ('value1', 'value2'),
       ('value1', 'value2'),
       ('value1', 'value2'),
       ...

PR Summary

• Modification of SqlDialect.java
  The update in the SqlDialect.java file removed a certain limitation with SparkSQL. Previously, it was unable to support batch operations (performing multiple tasks at once, which is faster and efficient). This limitation has been removed.

• Changes in SqlTest.java
  The changes in SqlTest.java was made to test the new batch insert capabilities of SparkSQL. A method has been updated to generate a batch insert statement with 10 rows, allowing us to verify and ensure the correct functioning of this new feature.
