Download page must link to https://www.apache.org/dist/spark for current releases

The download page currently uses the archive server:
https://archive.apache.org/dist/spark/...
for all sigs and hashes.
This is fine for archived releases, however current ones must link to the mirror system, i.e.
https://www.apache.org/dist/spark/...

Also, the page does not link directly to the hash or sig.
This makes it very difficult for the user, as they have to choose the correct file.
The download page must link directly to the actual sig or hash.

Ideally do so for the archived releases as well.
