Update the submission details page

[ThomasKranitsas]

Update the existing submission details page based on the following requirements:

• Use tabs layout based on the design below.
• The Review summary tab should be enabled by default.
• The Artifacts tab should render data fetched from the /challengeSubmissions/:submissionId/artifacts endpoint.
• Clicking the download icon on the Artifacts tab should call the /challengeSubmissions/:submissionId/artifacts/:artifactId/download endpoint to download the artifact. This should work similarly to how downloading the submission currently works.
