backend prod settings:

- set WEB_CONCURRENCY env var to configure number of backend api workers for both docker and k8s
- set via 'backend_workers' in values.yaml
- also add 'rwp_base_url' to values.yaml
- update containers to use public webrecorder/browsertrix-backend and webrecorder/browsertrix-frontend containers
- make liveness, readiness and startup health checks more tolerant
