Task

As an engineer working on RHDH, I want to align the homepage of the Rolling Demo AI RHDH instance with the vanilla RHDH so that people who are using it have a similar experience with the vanilla product.

Background

I have gone through the list of changes and in general is quite straight forward:

• We need to remove the ai-experience plugin and use the default homepage.
• Then we need to bring back the support button on the global header.
• The application launcher should have a bit less items.

Acceptance Criteria

• The rolling demo homepage follows the items described in the background.
