Change /all to /documents

[jeffdaley]

Moves the "All Docs" route from /all to /documents to give us a better framework to add new models, e.g., projects, products, teams, that can be browsed. References to the /all route are now redirected to /documents.

Do you think we should add an acceptance test for the redirect? (not sure offhand if this is possible, but if so, it might be able to catch regressions)

Thanks for catching this. I wrote one in my spike branch but forgot to bring it over. ✅
