feat(fish/config): add homebrew paths for arm64 and x86_64

This commit adds the homebrew paths to the fish shell configuration.
It checks the machine architecture and adds the appropriate homebrew
path. For arm64, it adds /opt/homebrew/bin and for x86_64, it adds
/usr/local/bin. This ensures that the correct homebrew binaries are
used depending on the machine architecture.
