command required -o org

The sample command gave me an error until I included the org name
`influx telegrafs create \
-n \
-d \
-f /path/to/telegraf.conf`
Throws error:
`Error: must specify org ID or org name`

Adding `-o ` succeeds.
We should change the docs to say:

`influx telegrafs create \
-n \
-d \
-o
-f /path/to/telegraf.conf`

Open the Telegraf configuration creation page at the linked URL and locate the sample `influx telegrafs create` command. Add the organization-name option shown in the issue, then verify the rendered documentation includes it and matches the working command.
