Add Container Examples to Docu Website Example Category

[Ndricim]

Somewhere on this section, maybe at the bottom, we could add an External Link to the Container Examples to give more exposure to the Container.

Investigate how the current external links are added there, and add the "Container Examples" link as well.

Note: Luigi Docu Page is in itself a Luigi Microfrontend based application. So the external option would be a Luigi node configuration. Search in our Docu how to add a new node on the left navigation that is shown with the external link icon, and add it appropriately.
