chore: [REL-4161] pass homebrew token through Makefile to Goreleaser (#551)

Okay, I think I finally understand why Goreleaser wasn't able to find
the HOMEBREW_GH_TOKEN. Setting it as an env var on the GHA is not
enough, it needs to be explicitly passed to the Makefile, and then
passed to the Goreleaser command.
