fix(ci): template CRDs apart of the chart package process

[anthr76]

.values.installCRDs appears to have the operator load the CRDs from helm values after a helm install/upgrade is processed. In argo helm installs are essentially templated out so the operator doesn't have a concept of what was set. So in CI we create a template for values.installCRDs on whether to install the CRDs or not via helm.

• Also ensure pushing of helm charts only happens on the default branch
• Disabled container builds on PRs unless the CI file was changed manual builds can be kicked off with a workflow_dispatch
