chore: support windows

[simoneb]

We're using this in https://github.com/nearform/fast-jwt and the logic to locate the runner module doesn't work on Windows.

In order to fix that, besides fixing the logic itself, I had to do a few more changes:

1. use cross-env to set env vars during test on Windows
2. update some swc dependencies because they would no longer resolve with newer versions of Node
3. updated the ci workflow to run the build across multiple versions of OS and Node. Note that I had to do a specific exclusion for the combination windows/Node 18 because the node:test test location algorithm has been changed and it wouldn't locate tests on Windows, on that specific version of Node. I thought this wouldn't be a big deal
4. minor changes here and there

I would appreciate it if you could review this, which only contains a minor functional change, and release a new version that we can consume in our downstream packages.

tests won't run on Windows just for Node 20.18.0. They run for newer versions so I thought it wouldn't be a big deal. Fixing this would not be easy otherwise
