fix: multiple docs issues (#8244)

# Which Problems Are Solved

- `<details>` tag is rendered in some cases in the docs, instead of
rendering a detail section which can be expanded
- New API V2 and V3 services where not rendered correctly
- The plugin which made it possible to integrate external code files and
show them on the docs didn't work anymore

# How the Problems Are Solved

- remove / from details tag, so it is properly rendered
- changing link source from tag to auto
- Someone already forked the repository and made it available for
docusaurus v3, we integrated the forked version
