Display the architecture (arm64 or x86) of the current shell in your prompt using Starship. I use zsh as my shell but you should be able to adapt this for other shells. As a bonus this also shows you how to set up your path to work with both arm64 and x86 versions of Homebrew.

Add this to your ~/.zshrc:

if [[ $(arch) == 'arm64' ]]; then
  export PATH="$HOME/bin:/opt/homebrew/bin:/opt/homebrew/sbin:$PATH"
  export SHELL_ARCH="arm64"
  echo '=========== arm64 ============'
else
