Add query example for pyarrow.flight FlightClient

Provide a v3 query example using `pyarrow.flight` `FlightClient`.
Add `pyarrow.flight` to Flight SQL clients reference.

Some sample code that doesn't yet work. Token authentication still apparently requires middleware or inserting the auth header in a way that isn't clear in the docs or code.

```py
from pyarrow.flight import FlightClient, Ticket, \
FlightCallOptions, Action, \
ClientMiddleware
import json
import pandas as pd
import os

DATABASE_NAME = os.getenv('CLOUD_SERVERLESS_BUCKET_NAME')
DATABASE_TOKEN = os.getenv('CLOUD_SERVERLESS_READ_WRITE_TOKEN')
INFLUXDB_HOST=os.getenv('CLOUD_SERVERLESS_HOST')

# influxql = "SELECT MEAN(elapsed) FROM home WHERE time >= '2023-04-07 19:35:19.314571143' AND time <= '2023-04-07 21:51:29.638717686' GROUP BY time(10m)"

client = FlightClient(f"grpc+tls://{INFLUXDB_HOST}:443")
token_bytes = bytes(f"Bearer {DATABASE_TOKEN}".encode('utf-8'))
token_pair = (b'authorization', token_bytes)
database = (b'database', bytes(DATABASE_NAME.encode('utf-8')))
options = FlightCallOptions(headers=[token_pair, database])

# do_action = client.do_action(action, options)

# client.authenticate(options)

def test_sql_query():

sql = "SELECT * FROM home where room like 'telegraf%'"

ticket_data = {
"sql_query": sql,
"query_type": "sql"
}

ticket_bytes = json.dumps(ticket_data)
ticket = Ticket(ticket_bytes)
reader = client.do_get(ticket=ticket, options=options)
arrow_table = reader.read_all()
# data_frame = arrow_table.to_pandas()
# print(data_frame.to_markdown())

test_sql_query()
```

##### Relevant URLs
- _Provide relevant URLs (issues, community threads, existing doc pages, etc.)_

Start with the provided pyarrow.flight FlightClient sample and the existing Flight SQL clients reference. Verify how token authentication works for the v3 query example, then document a working example and add pyarrow.flight to the client list. Done means the example runs with authentication and the reference includes the client.
