<!-- Thanks for opening a pull request! If you're new to Parquet-Format, information on how to contribute can be found here: https://parquet.apache.org/docs/contribution-guidelines/contributing Please open a GitHub issue for this pull request: https://github.com/apache/parquet-format/issues/new/choose and format pull request title as below: GH-${GITHUB_ISSUE_ID}: ${SUMMARY} or simply use the title below if it is a minor issue: MINOR: ${SUMMARY} --> ### Rationale for this change Per Parquet's requirements, we need at least two reference implementations to finalize the Variant logical type specification and here are the current status: Java already has the encoding and shredding implementations in place: https://github.com/apache/parquet-java/pull/3197 https://github.com/apache/parquet-java/pull/3202 https://github.com/apache/parquet-java/issues/3223 https://github.com/apache/parquet-java/issues/3211 Go also includes encoding and shredding support: https://github.com/apache/arrow-go/pull/344 https://github.com/apache/arrow-go/pull/434 Rust is currently working on the shredding implementation. In addition to these, we already have a full Variant implementation in Apache Iceberg, as well as in some closed-source engines. At this point, I think we have enough implementation coverage to move forward with finalizing the Variant spec. ### What changes are included in this PR?
