query_data_frame returns a list of data frames

Personne n'a encore pris cette issue.

### Specifications

* Client Version: 1.36.1
* InfluxDB Version: 2.71
* Platform: Linux

### Code sample to reproduce problem

Push a series of data and get it back via API query
```
for i in range(0,600000):
temperatura += 1
point = (
Point("Postazione1")
.tag("TipoTest", 1)
.field("Temperatura", temperatura))
DBresponse = write_api.write(bucket=bucket, org=config.influx_org, record=point)
time.sleep(.01)
```
Then get back the data with API AND THE QUERY BELOW
```
from(bucket: “Bed1”)
|> range(start: 2023-06-22T14:10:36.106Z, stop: 2023-06-22T14:29:12.154Z)
|> filter(fn: (r) => r[“_measurement”] == “Postazione1”)
|> filter(fn: (r) => r[“TipoTest”] == “1”)
|> filter(fn: (r) => r[“_field”] == “Temperatura”)
|> aggregateWindow(every: 1s, fn: mean, createEmpty: false)
|> yield(name: “mean”)
|> pivot(rowKey:[“_time”], columnKey: [“_field”], valueColumn: “_value”)
|> keep(columns:[“_time”, “Temperatura”])

client = InfluxDBClient(url=influx_url, token=influx_token, org=influx_org, debug=False)
df = client.query_api().query_data_frame(org=influx_org, query=query)
```

For some reason, `df` is a list of, in my case, 2 data frames so I can access `df[0]` and `df[1]`

Why I got 2 data frames and not one?

### Expected behavior

Return a single data frame with all the data from my measure

### Actual behavior

Return two data frames

Commencez par query_api().query_data_frame et reproduisez la requête Flux fournie avec l’exemple de client Python fourni. Comparez la liste de data frames renvoyée avec l’unique data frame attendu et déterminez quel comportement produit la requête.
