Broken link checking should not rely on readers

[timhunt]

What is the URL of the page where you experience the error?

Potentially all

What is the issue with this page?

Since the new docs are build by an automatic process, it should not be left to readers to find broken links like #186. The build system should find them. (Surely this is a standard feature of whatever package we are using?)

Are you able to provide a patch for this?

No response

Hi Tim,

We do have broken link checking, but it does not currently check anchors. I will raise a request in Docusaurus for this.

Raised upstream at https://docusaurus.io/feature-requests/p/broken-link-detection-should-check-anchors

This is actually non-trivial to implement but I'll have a think about how to do so.
