Markdown validation not validating markdown link fragments

[petertonysmith94]

We have links to sections on a page #typegen (see example). There is currently no validation to check that they exist and therefore, are broken.|

We should add validation to ensure that, all our links work as expects, so the user can navigate the documentation with ease.

Might be worth adding a CI job with a markdown link checker such as https://github.com/tcort/markdown-link-check

Like this one? .github/workflows/md-lint.yaml

Looks to me the rule no-dead-link is not being applied.
