DOCS-12847 Update links on Drivers index page (#514)

- Updates the links to outdated api.mongodb.com pages
- Ruby and Python still have up-to-date api.mongodb.com pages, so
I left those links alone.
- Updates the MongoDB University course links for Python, Java
and JS.
- Remove deprecated C# course link
