package init should offer tempate stack options to init from helm3 or kustomize

[displague]

What is the problem?

The current package init command expects to be invoked from a kubebuilder project.

Tempate stacks can be created with only helm3 or kustomize files.

What does it look like when it's done?

The init command should offer arguments to simplify the experience when working in this environment.

Should this be the default mode? Should the environment be detected (and overridable)?
