fix: PROJECT file is not updated with component workloads

[scottd018]

This specifically applies to a collection. Standalone workloads are added just fine and any followon workloads are added fine as well. Given the following PROJECT file in the root:

domain: mydomain.com
layout:
- go.kubebuilder.io/v3
multigroup: true
plugins:
  operatorBuilder:
    cliRootCommandName: opctl
    controllerImg: ""
    workloadConfigPath: .operator-builder/workload.yaml
projectName: myoperator
repo: github.com/myproject/myoperator
resources:
- api:
    crdVersion: v1
    namespaced: true
  controller: true
  domain: mydomain.com
  group: custom
  kind: MyResource
  path: github.com/myproject/myoperator/apis/custom/v1alpha1
  version: v1alpha1
  webhooks:
    conversion: true
    defaulting: true
    validation: true
    webhookVersion: v1

When using a collection, only the top-level collection is added. The components should also exist in this file. This helps when we get to the point where we need to create webhooks, as the create webhook command needs to know about the project metadata.
