Prerender routes on /vol1 and /doc to prevent 404

[vvvyyynet]

Make sure the following routes are prerender and don't lead to 404:

• https://dhbern.github.io/ACO/dokumente/vol1/
• https://dhbern.github.io/ACO/dokumente/vol2/
• https://dhbern.github.io/ACO/dokumente/vol3/
• https://dhbern.github.io/ACO/dokumente/vol1/CV166/

To solve this, the conflict with SearchParameters on the same routes must be resolved.
