Review Comment:
This part use `ls` with `-t` option, so we can't use `echo`.
I don't know alternate command which is usable on macOS / Linux.
(As far as I know, `find` and `stat` can't use the same option on macOS /
Linux)
```python
latest=$(python3 -c '
import glob, os
files = glob.glob("dist/pyarrow*.whl")
if files:
print(max(files, key=os.path.getmtime))
')
echo "$latest"
```
