fix: declare parquet-hadoop and parquet-common test deps in embedded-tests

The new Parquet EXTERN test references org.apache.parquet.hadoop
(ParquetWriter, CompressionCodecName) and parquet-common, which were only
present transitively. Declare them explicitly so maven-dependency-plugin's
analyze goal no longer fails on used-undeclared dependencies.
