@Fokko I see the Spark tests are failing with this error
```
java.lang.ExceptionInInitializerError
Caused by:
com.fasterxml.jackson.databind.JsonMappingException: Scala module
2.10.2 requires Jackson Databind version >= 2.10.0 and < 2.11.0
```
This happens because Jackson expects `com.fasterxml.jackson.core` versions
to match `com.fasterxml.jackson.module` and that doesn't seem to be the case
here. I ran a gradle build scan and seems like `jackson-databind` version is
being upgraded to 2.11 [because of Avro
1.10.0](https://issues.apache.org/jira/browse/AVRO-2853) which is causing this
issue.

I think we may need to bump Iceberg's jackson version in
[`version.props`](https://github.com/apache/iceberg/blob/01fca3d0a3c5653fe5a4a2a88c29aeaffca33f1d/versions.props#L14)
and in
[`build.gradle`](https://github.com/apache/iceberg/blob/01fca3d0a3c5653fe5a4a2a88c29aeaffca33f1d/build.gradle#L97)
@rdblue I am not a 100% sure if this is the right thing to do. I know Spark
can be finicky about the Jackson version. Do you have any insights here?
