SPARK-3404 [BUILD] SparkSubmitSuite fails with "spark-submit exits with code 1"

This fixes the `SparkSubmitSuite` failure by setting `<spark.ui.port>0</spark.ui.port>` in the Maven build, to match the SBT build. This avoids a port conflict which causes failures.

(This also updates the `scalatest` plugin off of a release candidate, to the identical final release.)

[SPARK-3448][SQL] Check for null in SpecificMutableRow.update

`SpecificMutableRow.update` doesn't check for null, and breaks existing `MutableRow` contract.

The tricky part here is that for performance considerations, the `update` method of all subclasses of `MutableValue` doesn't check for null and sets the null bit to false.
