Using Spark SQL at `DataFrameReader.load()` does break the current
dependency set.
Tests:
- Both JDBC integration tests fail at `SqlToRddOperator.java:134` with
`Could not deserialize ATN with version 3 (expected 4)`.
Resolved Spark dependencies are mixed:
- `spark-core`: `3.5.7`
- `spark-sql`, Catalyst, GraphX, MLlib: `3.4.4`
- Wayang resolves `antlr4-runtime:4.13.1`.
- Spark 3.5.7 declares ANTLR 4.9.3.
- `wayang-spark/pom.xml` also declares ANTLR 4.8.
The POM needs one `${spark.version}` for all Spark artifacts. The ANTLR
runtime must also be aligned or isolated. Updating Spark alone does not fix the
failure because Spark 3.5.7 still requires ANTLR 4.9.3.
Please fix the dependency alignment and rerun `SqlToRddOperatorTest`.
