Feature/assignment base repo link (KHO-338)

[ntietje1]

Summary

• Adds a backend endpoint for getting a base repo
• Changes assignment page's link from linking to the template repository to the base repository (you can still get to the template FROM the base repo)
• Adds reuse of the react query cache for assignments (blazingly fast speeds)
• Note: I accidentally branched off of workflow-rework
• Made a ticket for a UI minor bug KHO-337 (button styling issue)
