Update goreleaser (#16)

* Use correct goreleaser project name

Doesn't look like there were any side-effects of having the wrong
project name until now, fortunately.

* Update goreleaser to v2.x

This will hopefully fix the changelog issue we have been experiencing
(where the entire commit history was appearing on the changelog).
