So, Node requires generated ESM JS files need to have imports that end with `.js` (unless they are importing the root or declared export from a package... but for relative paths, this is a must). But we haven't quite figured out a way to get tsc to force us to do this... so if we mess it up, we only find out at runtime when trying to run a built ESM package. This doesn't even necessarily show up in our tests (Jest does its own thing a lot), and the new smoke-test doesn't cover all of our codebase. So we set up eslint with a particular rule that looks for this. As it happens, this rule doesn't check `import type` (import-js/eslint-plugin-import#2270) but fortunately `import type` doesn't matter to Node. We don't generally enable eslint: there are plenty of rules that we don't pass currently. We can consider adding some rules later as they are found to be valuable. For now we just run this one rule!
