Upgrade to using `apache-avro` 0.22

### Is your feature request related to a problem or challenge?

15 days ago the latest version (0.22.0) of `apache-avro` was released. This has come with approximately 34 breaking changes. This issue is to track upgrading to using it.

This in turn has internal fixes needed to get UUID partitions fully working in #2916

### Describe the solution you'd like

* `iceberg-rs` changes from using `apache-avro` version 0.21.0, to 0.22.0.
* All breaking changes fixed.
* No new bugs added.

(I can make a start on this as I need UUID partitions. I suspect there will be places in the code I'll need to reach out and ask what is the code trying to do, and asking what correct looks like.)

### Willingness to contribute

I would be willing to contribute to this feature with guidance from the Iceberg Rust community

Start by locating the dependency declaration and the code affected by the apache-avro 0.21.0 to 0.22.0 upgrade, then review the UUID partition work tracked in #2916. Work through the breaking changes with the Iceberg Rust community for guidance; done means the project uses 0.22.0, all breakages are fixed, UUID partitions work, and existing behavior has no new bugs.
