Linting no longer works in api/ and lib/

[ekzyis]

In 4fe4b5e, I had to exclude linting in api/ and lib/. It stopped working because I had to add a package.json with {"type": "module"} in these folders for #500.

A workaround to run the linting is to undo these changes but this breaks worker imports. So you can lint this way, but you can't run the code.

That's annoying. We should find a way to fix the error I wasn't able to fix mentioned in 4fe4b5e.
