How do I ping my phone with the new update?

The widget I used to ping my phones location is gone.

Technically, that's not a widget. It's the Control Center. And as Rudegar pointed out above, you now access that using the button on the side. Widgets, in the form of a Smart Stack are what now appears when you swipe up.

Use Control Center on Apple Watch - Apple Support

Use the Smart Stack to show timely widgets on Apple Watch - Apple Support

when I on my apple watch click on the pill shaped side button under the crown ping the phone is still there
