Review Comment:
Yeah, I found that the normal @xyz thing only works if the homebrew-core
repo includes multiple versions. Homebrew only seems to do this for popular
packages where people might need multiple versions, like node.js. For less
popular packages, like libmxml, they only support the latest version. Seems to
be a pretty basic package manager.
So essentially what this does is it creates a local repo (`brew tap-new`),
finds and extracts 3.3.1 out of the git history of homebrew-core into that
local repo (`brew extract`), and then installs that local version.
This is the only way I could find to do it. It seems kindof
developer-y/experimental, so it feels like it we might want it to just be a
short term solution. In the long term, we probably need to figure out why 4.x
doesn't work and see if we can support that. But this at least allows our CI to
pass.
