[Python] Can not refer to field in a list of structs

When the dataset has nested sturcts, "list",  we can not use `pyarrow.field(..)` to get the reference of the sub-field of the struct.

For example

 
```python

import pyarrow as pa
import pyarrow.dataset as ds
import pandas as pd

schema = pa.schema(
[
pa.field(
"objects",
pa.list_(
pa.struct(
[
pa.field("name", pa.utf8()),
pa.field("attr1", pa.float32()),
pa.field("attr2", pa.int32()),
]
)
),
)
]
)

table = pa.Table.from_pandas(
pd.DataFrame([{"objects": [{"name": "a", "attr1": 5.0, "attr2": 20}]}])
)
print(table)

dataset = ds.dataset(table)
print(dataset)
dataset.scanner(columns=["objects.attr2"]).to_table()
```

which throws exception:

```

Traceback (most recent call last):

```

Start by running the provided Python reproducer, then trace the pyarrow.field(..) reference through dataset.scanner(columns=["objects.attr2"]). The issue is done when selecting a sub-field of a list dataset succeeds and returns the expected table without ArrowInvalid.
