Status page out of date

The status page linked in the README, https://iceberg.apache.org/status/, seems to be out of date with respect to the features of this library. For instance, it looks like both positional and equality deletes are supported. I'm not sure what else is wrong there but I suspect there's quite a few features added since that was last updated.

Is there some more up to date source which could be linked?

Start with the status page linked from the README and compare its feature list with the current iceberg-rust project, including positional and equality deletes. Identify the most up-to-date source, then update the README link or status-page content so supported features are accurately represented. Done means the linked information reflects the library's current capabilities.
