🌱 Add bundle installer for sample projects in docs (#4281)

Add bundle installer for sample projects in docs

Introduces a bundle installer for sample projects, with config/default/kustomization.yaml settings uncommented to ensure complete bundle generation. This enhances review visibility by showing the final state of patches and Kustomize configurations directly in the generated bundle.

Motivation: Makes reviews more efficient by displaying final configurations directly in the bundle, with only relevant settings uncommented in config/default/kustomization.yaml for each sample.
