Fix broken external links

Here is the output of a check running on arkitekt.live which returned a list of broken links.

- [ ] we should fix those
- [ ] we should add a regular check of some sort to the CI

```docker run raviqqe/muffet https://arkitekt.live -v | grep 404 | uniq

Start by locating the Docusaurus documentation content containing the listed URLs, then rerun the provided muffet command against arkitekt.live to confirm which links still return 404. Review the repository's CI configuration before adding a regular link check. Done means the remaining broken links are resolved and the check runs regularly in CI.
