### What changes were proposed in this pull request?
Explicitly pass the series name in `convert_numpy`
### Why are the changes needed?
Arrow array from `batch.column(idx)` contains name, and this name will be
used to rename the pandas series returned by `array.to_pandas()`.
In `convert_legacy`, the first step is `array.to_pandas()`, so the name was
kept.
In `convert_numpy`, complex conversion happened before `to_pandas()`, and
this name will be dropped after pa.compute functions. We'd explicitly pass the
series name instead of relying on arrow internal stuff `array._name`
### Does this PR introduce _any_ user-facing change?
no
### How was this patch tested?
ci
### Was this patch authored or co-authored using generative AI tooling?
no
