Use JSON-LD link if found for HTML injection

[webb-ben]

Overview

Use JSON-LD link if found during link creation to render JSON-LD in default HTML templates. For requests that require a parameter like EDR, pygeoapi throws an error when trying to inject the JSON-LD to the HTML template because it does not include the necessary query arguments. This PR updates the behavior such that if a JSON-LD link is found, it is then subsequently used to fetch the json-ld that is injected because it will contain the additional query arguments to fetch the appropriate url.
