As promised in #23817, I have this made a PR to make Release Download
URLs predictable. It currently follows the schema
`<repo>/releases/download/<tag>/<filename>`. this already works, but it
is nowhere shown in the UI or the API. The Problem is, that it is
currently possible to have multiple files with the same name (why do we
even allow this) for a release. I had written some Code to check, if a
Release has 2 or more files with the same Name. If yes, it uses the old
`attachments/<uuid>` URlL if no it uses the new fancy URL.
I had also changed `<repo>/releases/download/<tag>/<filename>` to
directly serve the File instead of redirecting, so people who who use
automatic update checker don't end up with the `attachments/<uuid>` URL.
Fixes#10919
