make test doesn't use polygott-lang-setup

[andyli]

It seems that make test does not use polygott-lang-setup, shouldn't it?

Full context:

I'm working on Haxe language support, and I want to write a config file next to the entrypoint in the project directory. I tried to use

runtimeSetup = [
  "echo '--run Main' > /home/runner/run.hxml"
]

But it seems to have no effect when running make test-haxe.
