fix(release): replace deprecated 'folder' field with 'directory' in GoReleaser config

The 'folder' field in the homebrew brew configuration was deprecated
in GoReleaser v2.x and replaced with 'directory'. This was causing
the release workflow to fail with:
  "field folder not found in type config.Homebrew"

Changes:
- Updated .goreleaser.yml:169 to use 'directory' instead of 'folder'

Fixes release workflow failure in run #21913974032
