Sean Owen 5e120e4651 [SPARK-34507][BUILD] Update scala.version in parent POM when changing Scala version for cross-build
### What changes were proposed in this pull request?

The `change-scala-version.sh` script updates Scala versions across the build for cross-build purposes. It manually changes `scala.binary.version` but not `scala.version`.

### Why are the changes needed?

It seems that this has always been an oversight, and the cross-built builds of Spark have an incorrect scala.version. See 2.4.5's 2.12 POM for example, which shows a Scala 2.11 version.
https://search.maven.org/artifact/org.apache.spark/spark-core_2.12/2.4.5/pom

More comments in the JIRA.

### Does this PR introduce _any_ user-facing change?

Should be a build-only bug fix.

### How was this patch tested?

Existing tests, but really N/A

Closes #31801 from srowen/SPARK-34507.
