[feature request] provide a quick way to get the version of scala-update being used

[ckipp01]

Hello! 👋🏼

The problem

So today I was trying this out with a Mill project since I saw you recently added support for this. These are the steps I took:

• brew install kitlangton/tap/scala-update
• git clone [email protected]:com-lihaoyi/cask.git && cd cask
• scala-update

Here I was told

All of your dependencies are up to date! 🎉

But that's not true currently in cask as there are many deps out of date. Since I recently saw that Mill support was added I wanted to verify the version of my scala-update was the latest so I tried -h and a couple other commands, but couldn't get the version to verify I was on the newest.

Expectation

I'd expect to be able to pass in a -h or version command or even in like grayed out text be able to see the current version of scala-update on the screen that shows SCALA UPDATE COMMANDS.

Ahoy, Chris! Great idea! Will do 😄

Mill support was added via a PR, and may not be complete. I'll follow your steps and see if I can fix it—assuming it's more than just a version issue.
