Fixes#10197
# Important Notes
From now on, package installation will be using `pnpm install`. Installing it globally is fine for convenience, but it can also be used as `corepack pnpm install` without having to install anything other than node. For now, all other scripts are still invoked using `npm`, so we can still invoke them with usual `--workspace` setting. As far as I can tell that doesn't really have any other side effects and is identical as running the script through `pnpm run` in respective workspace project subdirectory.
Implementing most parts of the Documentation Panel in the new GUI.
Known issues:
- Links do not work (yet, covered by #7992)
- Some pages are entirely empty – I’m investigating. Missing doc sections likely cause this, so we probably want to add some placeholder.
- Tags do not look as in design. I tried implementing them correctly but didn't have enough time to finish everything. Some initial implementation is in place, though. I will create a separate task for them.
