Review Comment:
Aaa..... 🤔
The PR Title - ` implement predicate adaptation for nested structs` and
```
Functionality equivalent to https://github.com/apache/datafusion/pull/16371
but for https://github.com/apache/datafusion/pull/16461.
```
gave me the expectation that this PR implements nested struct adaption
already.
