Observed issues

The Cucumber file features/hello.steps.mjs can not resolve these paths that come from SvelteKit, like this line:

import { showBrowser } from '$lib/mylib.mjs'`

which fails showing this:

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '$lib' imported from /issue/cucumber-sveltekit-repro/features/hello.steps.mjs

or like this other line:

import { showBrowser } from '../src/lib/mylib.mjs'`

which fails showing this, as showed above:

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '$app' imported from /issue/cucumber-sveltekit-repro/src/lib/mylib.mjs
