FutureWarning: `pyarrow.feather.write_feather` is deprecated as of 24.0.0.

Description of new feature

We started getting FutureWarning and while #4198 temporarily allows unrelated PRs to pass this needs to be fixed properly:

warnings.warn(
            "pyarrow.feather.write_feather is deprecated as of 24.0.0. "
            "Use pyarrow.ipc.new_file() / RecordBatchFileWriter instead. "
            "Feather V2 is the Arrow IPC file format.",
            FutureWarning,
            stacklevel=2
        )
E       FutureWarning: pyarrow.feather.write_feather is deprecated as of 24.0.0. Use pyarrow.ipc.new_file() / RecordBatchFileWriter instead. Feather V2 is the Arrow IPC file format.

Hi, I'd like to work on this issue as one of my first contributions to Awkward Array. I hit the same FutureWarning locally in test_2683_to_and_from_feather.py (test_simple and test_complex) while setting up my dev environment.
My plan is to update ak_to_feather.py to use pyarrow.ipc.new_file() / RecordBatchFileWriter instead of the deprecated pyarrow.feather.write_feather, matching the API migration suggested in the warning itself. I'll also check whether ak_from_feather.py needs any corresponding changes.
Could someone assign this to me? Happy to open a draft PR to track progress once I've read through the relevant code.

Thanks, planning to migrate both to_feather and from_feather to pyarrow.ipc, I am currently following the pattern from #4198 discussion.
