fix: Adapt to recent changes in JDK download URL response

Parse the JDK redirect URL for a case insensitive redirect location

https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/307 shows the response as:

> location: /en-US/docs/Learn/JavaScript/Client-side_web_APIs/Fetching_data
> content-type: text/plain; charset=utf-8
> date: Fri, 19 Jul 2024 12:57:17 GMT

Previously, the response must have used "Location:" rather than "location:"
