### Describe the bug, including details regarding any error messages,
version, and platform.
I have a table with lots of strings that I would like to export to Pandas.
The following code can recreate the error:
```python
import numpy as np
import pyarrow as pa
SIZE = 1024
N = 2 * 1024 * 1024
buffer = np.random.bytes(N * SIZE)
table = pa.Table.from_pydict({
"row": [buffer[i * SIZE: (i + 1) * SIZE] for i in range(N)]
})
df = table.to_pandas(strings_to_categorical=True)
```
This is currently failing with the error:
```
Traceback (most recent call last):
File "/home/alandu/workspace/scratch/repro.py", line 13, in <module>
df = table.to_pandas(strings_to_categorical=True)

pyarrow.lib.ArrowCapacityError: array cannot contain more than 2147483646
bytes, have 2147483648
```
This is using Python 3.10 on PyArrow 17.0 on Linux (installed via
conda-forge).
This *only* seems to happen when I set `strings_to_categorical=True` -- if
that is `False`, then I can export this to a dataframe without issues.
