Add /opt/homebrew/bin to $PATH when present and a directory

`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`.

We now add a list of potential directories to `$PATH` if they exist
and are directories.

Closes #24
