You can't. `bitcoin-cli` has never had the capability to send alerts. It is not possible for a user to push out an alert from any Bitcoin Core node.

Alerts were sent by using a specially modified version of Bitcoin Core which had the particular alert to be sent hard coded into it. Developers have to modify Bitcoin Core and include the alert code in a local build every time they wanted to send an alert.
