fix(ci): wrong version published when two tags point to same commit (#392)

The tags v1.14.0-rc.2 and v1.14.0 point to the same commit. Goreleaser
always releases v1.14.0-rc.2 and we don't get a proper v1.14.0 release.

By specifying the release that goreleaser should handle, we can rely on
Github to specify the correct tag for the current workflow.
