use argocd default project

[nabuskey]

fixes: #42

As discussed in the issue above, we will use the default project for this release to ensure all embedded apps deploy. I also fixed the default kind image tag.

kubectl get applications -n argocd -o custom-columns="NAME":.metadata.name,"PROJECT":.spec.project
NAME                                       PROJECT
crossplane-helm                            default
idpbuilder-local-gitserver-argocd          default
idpbuilder-local-gitserver-backstage       default
idpbuilder-local-gitserver-crossplane      default
idpbuilder-local-gitserver-nginx-ingress   default
