“New” tag -

The context
This is left over from when we had separate install/uninstall URLs specified here. In 2022 The “Manage > Webhooks” page was added and the above section was deprecated and we were required to move to the new App Events Webhook.

This is now outdated.

On the flip side, on the “Webhooks” page - its still called “New” nearly two years later.
