fix: client command example using v2 option

[Ryuheeeei]

The examples of these three commands are based on hydra v1 cli option.

• hydra create client
• hydra import client
• hydra update client

When I follow the examples using hydra v2 cli, it didn't work. I got the message like unknown shorthand flag: 'n' in -n.
I updated these three commands example using v2 option.

This isn't hydra import client command. Instead, it seems hydra create client, right ?
According to https://www.ory.sh/docs/hydra/cli/hydra-import-client, it seems hydra create client. Sorry if I misunderstood.

The CommandPath variable automatically sets the correct name for the help command, so the previous version was correct :)
