`dependencies` ordering

### What happened?

I want to `helm install` customized https://github.com/cloudnative-pg/charts chart and hits a missing-CRDs error. I have the following dependencies defined in `Chart.yml`:
```
dependencies:
- name: cloudnative-pg
version: "v0.28.0"
repository: https://cloudnative-pg.github.io/charts
- name: cluster
version: "v0.6.0"
repository: https://cloudnative-pg.github.io/charts
```
and `helm install` hits this error:
```
$ helm install postgresql-cluster PostgreSQL_Cluster/
Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: resource mapping not found for name: "postgresql-cluster" namespace: "default" from "": no matches for kind "Cluster" in version "postgresql.cnpg.io/v1"
ensure CRDs are installed first
```

### What did you expect to happen?

`helm install` the dependencies in listed ordering.

### How can we reproduce it (as minimally and precisely as possible)?

`helm install` this chart: https://github.com/khteh/Kubernetes/tree/master/PostgreSQL/PostgreSQL_Cluster
