📘 DOC: Lint for broken links in all languages

[jasikpark]

Currently we have a yarn lint:linkcheck:local command that can check for broken links, but we don't have any way to switch what language you're using without JS, so it only checks the English pages.

I want to write a script using the programmatic version of blc to check all translations of the docs for broken links!

This is old, and possibly out-of-date, but is this something you might be interested in exploring, @hippotastic ? Even if only to triage and let me know whether to close this issue, or to try and tackle it yourself?

Sure @sarah11918, why not! I'll have a look 🙂

I've implemented it myself. See my PR above. The output looks like this:

  ❌ https://docs.astro.build/quick-start
  ❌ https://docs.astro.build/installation
  ❌ https://docs.astro.build/reference/builtin-components

[...]

*** Found 76 broken links.

When a link leads to a 404 page, the target href is prefixed by a ❌.
When the target page exists, but the link contains an URL hash that does not exist on that page, the prefix is 🔗.
