[Feature] Expose anchors in index.json

[caugner]

What information was incorrect, unhelpful, or incomplete?

A page can have several anchors, which are used both to deep-link between content, and to link from e.g. BCD data.

However, it is not straight-forward to validate that an anchor exists on a page, without crawling the page.

(Does rari validate anchors on internal links?)

What did you expect to see?

It would be nice if the index.json would include a list of all anchors in the content.

This would make it easier:

1. to validate mdn_urls in BCD with hashes,
2. to map en-US anchors to translated anchors (*).

(*) Note that BCD links with fragments uses en-US hashes, but since the mdn_url doesn't contain a locale, users might get redirected to another locale where the anchor doesn't exist.

Do you have any supporting links, references, or citations?
