[Bug]: Cannot write FixedSizeList data from Rust when using the default "item" inner field name

### What happened? Basically the same issue as #3566, but because that was fixed in the Python wrapper, you still get this error when writing with Rust: ``` Error: ArrowError(InvalidArgumentError("column types must match schema types, expected List(Int32, field: 'element') but found List(Int32) at column index 0"), Some("")) ``` ### Expected behavior You can write Arrow fixed-size list data and it's stored as a Delta Lake `List` column. ### Operating System Linux ### Binding Rust ### Bindings Version 20bdf3c2c62416923fe327bd0e41976627f143ec ### Steps to reproduce I'll make a PR that includes a unit test to reproduce this. ### Relevant logs ```shell ```
