Bash syntax error on v2/api/query/

_There's a bash syntax error on the documentation of the request samples of_ __v2/api/query/__

Here's the content of the bash request sample:
```bash
curl --request POST 'INFLUX_URL/api/v2/query?org=INFLUX_ORG' \
--header 'Content-Type: application/vnd.flux' \
--header 'Accept: application/csv \
--header 'Authorization: Token INFLUX_API_TOKEN' \
--data 'from(bucket: "example-bucket")
|> range(start: -5m)
|> filter(fn: (r) => r._measurement == "example-measurement")'
```

There's a missing closing quote from the line `--header 'Accept: application/csv \`.
It's apparent from the syntax highlighting on the web page and on this markdown snippet.

##### Relevant URLs
- [_v2/api/v2/#tag/Query_](https://docs.influxdata.com/influxdb/v2/api/v2/#tag/Query)

Open the v2/api/v2/#tag/Query documentation and locate the v2/api/query request sample. Check the Bash curl snippet around the Accept header, then verify the rendered page and Markdown syntax highlighting; done means the sample has balanced quotes and displays as valid Bash.
