Removing dist/ & testing against Stimulus 3

Hi!

This was mainly motivated to add support for Stimulus 3... but I think the library already supports it just fine, as this library never actually *imports* Stimulus itself (other than in a test file).

So, this PR includes a number of other "chores" that we should handle:

* The `dist/` directory is not needed, because this is used purely as a node package. Babel IS still there, because it's used by jest to transform the test controller file.
* The `src/setup.js` file was missing (there was a `dist/setup.js` file but the original source file was missing - but easily reproduceable).
* We're now testing against Stimulus 3.
