Sync groups from Keycloak to Outline

Usage

Assuming you have a self-hosted Outline Wiki and Keycloak setup running, do the following:

Add the webhooks service to your docker-compose.yml
Save the server.ts to webhooks/server.ts (relative to your compose file)
Save webhooks.env into the same folder as your compose file
Via your webserver configuration add a subdomain, eg webhooks.wiki.yoursite.org to forward to your webhook service port 8000
