[DOC-560] OpenAPI fields anchor links

[dandimeo]

Description

• OpenAPI fields are searchable within browser search; if fields are hidden, they will be automatically expanded
• Every field has an anchor link and generates an URL fragment within the URL, so that it can be easily shared as a link

If you use in-page search, options expand if they contain a match - this is great - but there is a slight problem: the icon that indicates the expand/collapsed state is not updated and then shows the opposite state (it's like > even though in-page search expanded it, then you click it to collapse and it becomes v as if it was expanded)

There are some anchor collisions, e.g. the collection path parameter and request body parameter here: https://deploy-preview-218--docs-hugo.netlify.app/3.11/develop/http/graphs/named-graphs/#replace-an-edge-definition

Otherwise, everything seems to work nicely.

Works great!
