Docs for fetch() have dangling reference to Response class

[peterflynn]

Description of the issue

The page https://adobexdplatform.com/plugin-docs/reference/uxp/function/fetch.html says @see Response for the return type, but it's not a clickable link.

Proposed solution

Should we just link to https://developer.mozilla.org/en-US/docs/Web/API/Response from there? Are there any significant differences from the web standard that we'd need to note?
