mac os instructions, brew command correction

[softminus]

brew install --cask ./vagrant.rb

needs to be

brew reinstall --cask ./vagrant.rb otherwise it gives an error

It's using an assumed starting point of a new laptop with no extra stuff installed, but of course steps can be adapted as needed to fit the situation.

i did start with a clean brew install with nothing installed (having wiped the machine to downgrade it from a monterey macOS beta), it's just that when running all three commands:

$ curl -O -L https://github.com/Homebrew/homebrew-cask/raw/015bd57c9637d517f1a814e46a1ece5de570c263/Casks/vagrant.rb
$ brew install vagrant
$ brew install --cask ./vagrant.rb

as suggested in https://github.com/zcash/zcash-gitian/blob/master/dependency_install_steps_by_platform/macOS.md, the last command gives an error:

oh, that's the mistake. I meant to replace brew install vagrantwith brew install --cask ./vagrant.rb, not add a new command. Good catch again!

Ohh ok! i just ran those three commands in order thinking that perhaps the install of vagrant from the repo was necessary to get the dependencies for the custom vagrant version! but if installing from the vagrant.rb works fine then there was no need!
