fix: correct YAML heredoc indentation in release workflow

The heredoc content for Homebrew formula generation had no indentation,
which broke YAML parsing (literal block scalars require consistent
indentation). Fixed by indenting the heredoc content to match YAML
block level, then using sed to strip the indentation from the output.
