Subject: [VOTE] Release Apache Iceberg ${version} RC${rc}

Hi Everyone,

I propose that we release the following RC as the official Apache Iceberg ${version} release.

The commit ID is ${release_hash}
* This corresponds to the tag: apache-iceberg-${version}-rc${rc}
* https://github.com/apache/iceberg/commits/apache-iceberg-${version}-rc${rc}
* https://github.com/apache/iceberg/tree/${release_hash}

The release tarball, signature, and checksums are here:
* https://dist.apache.org/repos/dist/dev/iceberg/apache-iceberg-${version}-rc${rc}

You can find the KEYS file here:
* https://dist.apache.org/repos/dist/dev/iceberg/KEYS

Convenience binary artifacts are staged on Nexus. The Maven repository URL is:
* https://repository.apache.org/content/repositories/orgapacheiceberg-<ID>/

Please download, verify, and test.

Please vote in the next 72 hours.

[ ] +1 Release this as Apache Iceberg <VERSION>
[ ] +0
[ ] -1 Do not release this because...
