User Story

As a developer, I want to view different versions of the stack in the devfile registry viewer, so that see all the stacks that are available in the public community registry.

Acceptance Criteria

• Expose multiple versions of the stack in the devfile registry viewer on the page that displays the individual stack
• Allow user to switch between different versions of the stack
• The default version of the stack is selected by default as specified by the stack provider
• Provide a filter on the main page to view stacks/samples based on the schema specification (lower priority)
