Removes the "archive version" override for the `shadowJar` task in the
build file, resulting in a jar-file that contains the current version
number in the filename. It's mostly a convenience tradeoff; either we
can see the version directly in the filename and avoid assumptions, or
we can easily overwrite an existing jar-file with a new one.
Also updates the upload step of the build workflow to a glob pattern so
we grab the file regardless of the version.
