PR Review Summary: REJECT

This upgrade of beam.version from 2.25.0 to 2.74.0 breaks the compilation.

Details:
The build fails with "cannot find symbol: class AvroCoder" errors.
In newer Beam versions (2.52.0+), AvroCoder has been moved to a separate extension module.

Required Changes to Merge:

1. Add the beam-sdks-java-extensions-avro dependency to pom.xml.
2. Update imports in MyDummyEvent.java and PaneGroupMetadata.java to use org.apache.beam.sdk.extensions.avro.coders.AvroCoder.
