Fix --password option for CLI documentation

[hassanahmadkhani]

In https://trino.io/docs/current/client/cli.html#authentication
seems required to edit and change as below :

--password parameter also required in cli command after setting TRINO_PASSWORD environment variable.

export TRINO_PASSWORD='LongSecurePassword123!@#'

The password is automatically used in any following start of the CLI if we use --password in cli as below:

./trino --server https://trino.example.com --user=exampleusername --password
