Show pipeline level config for pipeline template in the validator

[VonnyJap]

What happened:

The validator does not display pipeline level configuration when validating a pipeline template.

What you expected to happen:

The validator should also display all pipeline-level configurations.

How to reproduce it:

Paste this config into the validator

namespace: sd-test
name: example-template
version: '1.0.0'
description: An example pipeline template for testing golang files
maintainer: foo@bar.com

  subscribe:
    scmUrls:

  shared:

    environment:
