Make download submission for tutors functionality accessible from multiple places

[florian-glombik]

Is your feature request related to a problem?

When monitoring student progress for programming exercises teaching assistants often clone the student submission and run the tests locally to identify and resolve issues.

Describe the solution you'd like

With https://github.com/ls1intum/Orion/pull/56 Orion offers the functionality to download student submissions, integrated into a test project setup. It would be great if this functionality can be accessed from multiple places in Artemis.

I found the following places that would be beneficial to be supported:

• Participation view Often used when students report problems with the exercise/tests and a teaching assistant
• Scores view
• Assessment Dashboard Submission view

Describe alternatives you've considered

The teaching assistants can also do this manually, but this takes time that should rather be spent on resolving issues.

While I don't think it makes too much sense to add the buttons on the participation and scores page since Artemis does not offer a link to the assessment there either, the table in the submission page could be adapted to behave like the table in the assessment dashboard - showing a button to open the exercise when its not open and offering to download the assessment when the right project is opened
