Add get packages sub-command

[hodgiwabi]

• Unify get command output formatting
  • yaml-consistent three-dash start of file enables output yaml parsing
  • lowercase keys
  • key: value spacing for secrets.data and packages.spec.credentials

• Add packages output template

• Common go:embed moved to root.go file

Don't forget to update the README.md page and enhance the test cases ;-)

Thanks for working on this. This template file is not meant to be YAML parseable though. I know it looks like one but it's meant for humans to read the outputs easily. We have a yaml output option for yaml parsing purposes:

idpbuilder/pkg/cmd/get/secrets.go

Lines 179 to 198 in e8e2319

	func printOutput(templatePath string, outWriter io.Writer, data []any, format string) error {
	switch format {
	case "json":
	enc := json.NewEncoder(outWriter)
	enc.SetEscapeHTML(false)
	enc.SetIndent("", " ")
	return enc.Encode(data)
	case "yaml":
	b, err := yaml.Marshal(data)
	if err != nil {
	return err
	}
	_, err = outWriter.Write(b)
	return err
	case "":
	return renderTemplate(templatePath, outWriter, data)
	default:
	return fmt.Errorf("output format %s is not supported", format)
	}
	}

I honestly do not know if we can get this kind of data right now.
