chore(helm): switch from Deployment to StatefulSet (#1901)

Browse Source 
Jellyseerr is not designed to support multiple concurrently running instances.
To ensure that only one instance can run at any given time we:

- Replace Deployment with StatefulSet: switch from running "at least N pods" to
  "at most N pods".
- Remove replicaCount value: default is 1, we do not want to support more.

## Update Notes
### Updating to 2.7.0
Jellyseerr is a stateful application and it is not designed to have multiple replicas. In version 2.7.0 we address this by:
- replacing `Deployment` with `StatefulSet`
- removing `replicaCount` value
If `replicaCount` value was used - remove it. Helm update should work fine after that.
