Adds docker compose examples (#1113)
This adds three example docker-compose files:

- A basic Grist instance backed by sqlite, with no additional services.
- A Grist instance that uses Postgres, Redis and MinIO.
- A Grist instance that uses OIDC authentication and traefik.

These are intended to be customised by self-hosters for their own needs.

All examples should work without any additional configuration.
