Pandas outputs warning when calling dataframe.append in flux_csv_parser._prepare_data_frame

Nadie ha tomado este issue todavía.

### Specifications

* Client Version: 1.36.0
* InfluxDB Version: 2.7

### Code sample to reproduce problem

```python
query_api.query_data_frame(query)
```

### Expected behavior

The query should be executed without warnings.

### Actual behavior

Pandas outputs a FutureWarning:

```
/usr/local/lib/python3.11/site-packages/influxdb_client/client/flux_csv_parser.py:256: FutureWarning:
The behavior of array concatenation with empty entries is deprecated. In a future version, this will no longer exclude empty items when determining the result dtype. To retain the old behavior, exclude the empty entries before the concat operation.
```

This is related to the this code snippet:

### Additional info

In the recent pandas version handling of concatenation of empty dataframes changed, see https://github.com/pandas-dev/pandas/issues/39122. This should be handled else wise to reflect the changes in pandas.

Comienza en influxdb_client/client/flux_csv_parser.py alrededor de las líneas 243-256, donde query_data_frame construye el dataframe, y reproduce la advertencia con query_api.query_data_frame(query). Compara el comportamiento con el cambio de concatenación de pandas descrito en pandas issue 39122. Se considera terminado cuando la consulta se ejecuta sin la FutureWarning indicada.
