Add 'cs setup' tests

[julienrf]

Requires a release of Coursier after coursier/coursier#2657 is merged.

Interesting, it failed with “no main class found” during the cs setup execution: https://github.com/VirtusLab/coursier-m1/actions/runs/3985837517/jobs/6834993515#step:7:351

I won’t be able to look at the underlying issue, unfortunately. If someone with an M1 architecture wants to help, that would be very much appreciated!

It fails because cs setup tries to install sbtn, and while doing so it tries to build a native launcher (because there is no one yet on macOS and aarch64, see sbt/sbt#7143), and fails to do it.

I cannot reproduce the issue locally. cs setup did work on my M1:

./cs setup --jvm 17  
Checking if a JVM is installed
  No JVM found, should we try to install one? [Y/n] y
  Should we update ~/.profile, ~/.zprofile? [Y/n] 
Some shell configuration files were updated. It is recommended to close this terminal once the setup command is done, and open a new one for the changes to be taken into account.

Checking if ~/Library/Application Support/Coursier/bin is in PATH
  Should we add ~/Library/Application Support/Coursier/bin to your PATH via ~/.profile, ~/.zprofile? [Y/n]
