ci: fix target for homebrew tap

This got missed in the original migration in 06484a3 which replaced
github.com/cuelang with github.com/cue-lang. In the GoReleaser config,
"cuelang" appeared bare.

Per goreleaser/goreleaser#2355 there is no
good way to test all parts of a GoReleaser config until release time,
hence we continue to iron out these issues in subsequent beta releases.
