Automate setup of webhooks

[burggraf]

Chore

Describe the chore

Create a function to automatically configure Stripe webhooks using the configured Stripe secret(s). (This may not be necessary if there's only one or two webhooks to be configured. If there are a lot, this would save considerable time, especially if the local Docker environment changed.)

Additional context

In creating my MailGun interface for Postgres, I wrote a function that would automatically configure all the webhooks once we 1. had access to the api since the secrets were configured, and 2. had the path to our server. It sounds like this is something we could to to make setup quicker.
