Check link anchors in mdbook docs?

[roberth]

Is your feature request related to a problem? Please describe.

mdBook isn't capable of checking the anchors that are linked to (bla.html#foo -> anchor: foo) An extra tool could do this for us.

Describe the solution you'd like

I've solved this with linkchecker

• https://github.com/hercules-ci/flake.parts-website/pull/111/files

We could do the same and make it a separate check so that the nix package does not need another dependency.

Describe alternatives you've considered

Review carefully and wait for users to hopefully report the things we missed; busywork for everyone.

Wouldn't this require network access?

[roberth]

It defaults to checking internal links only.

I could also add a networked check with Hercules CI if you like. It can be synchronous on each push, merge, daily, or a combination.
