feat(webhooks): add name to webhook (#12641)

## Description

When working with webhooks, it's easy to lose track of which URL is
which. Adding a `name` (optional) column to the webhook model is a
straight-forward solution to make it significantly easier to identify
webhooks.

## Type of change

- [x] New feature (non-breaking change which adds functionality)

## How Has This Been Tested?

Model and controller specs, and also running in production over several
months without any issues.
