chore: bump iceberg-rust dependency to latest [iceberg]

[mbutrovich]

Which issue does this PR close?

N/A.

Rationale for this change

Take advantage of upstream reader performance optimizations:

• perf(reader): Add Parquet metadata size hint option to ArrowReaderBuilder iceberg-rust#2173
• perf(reader): Pass data file size and delete file size to reader to avoid stat() calls iceberg-rust#2175

What changes are included in this PR?

• Bump iceberg dependency in Cargo.toml
• Add Parquet metadata size hint that defaults to DataFusion's
• Serialize file sizes for Iceberg data files and delete files. Unfortunately, this surfaces an Iceberg bug (Missing size rewrite in rewrite_table_path for delete file iceberg#12554) so we still have to issue a stat() on delete files. I am fixing in upstream Iceberg

How are these changes tested?

Existing tests. I also ran IcebergReadFromS3Suite locally (since it's not run in CI) to verify that reading a delete file's size in an object store works.

Let's get DF52 in first, then I'll jump to an even newer iceberg-rust commit since they just picked up DF52 as well.

Draft since I want to pick up the DF52 changes in iceberg-rust, and hopefully apache/iceberg-rust#2181 will merge soon too.
