Fixes some Helm templating issues when setting up a deployment with an
existing database / signing keys.
- Allows for `.Values.postgresql.enabled: false` as long as
`.Values.global.dendrite_config.database.connection_string` is defined
- Allows for '.Values.signing_key.create: false' if
`.Values.signing_key.existingSecret` is set
Also fixes an error in the template resulting in profiling port not
being set correctly:
```
Error: template: dendrite-meta/charts/dendrite/templates/deployment.yaml:60:35: executing "dendrite-meta/charts/dendrite/templates/deployment.yaml" at <$.Values.global.profiling.port>: nil pointer evaluating interface {}.port
```

I do not know, how you run helm-docs ....
otherwise i would like to add somewhere:
````markdown
* Works well with [Prometheus Operator](https://prometheus-operator.dev/) ([Helmchart](https://artifacthub.io/packages/helm/prometheus-community/kube-prometheus-stack)) and there setup of [Grafana](https://grafana.com/grafana/), by enabling following values:
```yaml
prometheus:
servicemonitor:
enabled: true
labels:
release: "kube-prometheus-stack"
rules:
enabled: true # will deploy alert rules
additionalLabels:
release: "kube-prometheus-stack"
grafana:
dashboards:
enabled: true # will deploy default dashboards
```
PS: The labels `release=kube-prometheus-stack` is setup with the helmchart of the Prometheus Operator. For Grafana Dashboards it maybe need scan enable to scan in correct namespaces (or ALL), enabled by `sidecar.dashboards.searchNamespace` in [Helmchart of grafana](https://artifacthub.io/packages/helm/grafana/grafana) (which is part of PrometheusOperator, so `grafana.sidecar.dashboards.searchNamespace`)
````
Maybe also put somewhere the Screenshot of that Grafana Dashboard:

@S7evinK do you take a look?

As discussed yesterday, a simplified version of [my
helm](https://github.com/S7evinK/dendrite-helm) which deploys a monolith
with internal NATS and an optionally enabled PostgreSQL server. If the
PostgreSQL dependency is not enabled, a user specified connection string
is constructed.
