v1.3.1
brew doesn't always use /usr/local/bin any more, and macOS doesn't pass the $PATH from .zshrc/.bashrc to GUI applications which caused problems with a brew-installed version of lima.
prep_environment_for_lima() now adds a list of potential directories to $PATH if they exist and are directories - currently /usr/local/bin, /opt/homebrew/bin and /opt/local/bin.
Closes #24
