[IcebergIO] Raise Java 17 floor for IcebergIO's Java 11 dependents

Bumping the iceberg module to Java 17 (Iceberg 1.11.0 dropped Java 11)
breaks the Java 11 modules that depend on it, because Gradle's
JVM-version variant resolution refuses to let a Java 11 consumer depend
on a Java 17 library. Raise requireJavaVersion 11 -> 17 in:

  - sdks/java/extensions/sql/iceberg
  - examples/java/iceberg

The Java IO expansion service (sdks/java/io/expansion-service) also
depends on IcebergIO but was already raised to Java 17 on master in
#38974 (for Delta Lake), so it needs no change here.

For #38925

   However fixing forward is recommended.
 * (Java) IcebergIO now requires Java 17 at runtime. This raises the floor in preparation for the Iceberg 1.11.0 upgrade, which is published as Java 17 bytecode. Pipelines using `Managed.read(ICEBERG)`/`Managed.write(ICEBERG)` must run on a Java 17+ JVM ([#38925](https://github.com/apache/beam/issues/38925)).
