ci: Fix actorInput e2e test

[janbuchar]

• closes Fix E2E tests and release new version #559
• The package.json in the actorInput test directory made node.js import resolver used in actorInput/test.mjs think that it's in a package, so it couldn't find the apify package
• We'll need to restructure the test Actors later on to prevent this kind of issues - the test code and the actor source should be clearly separated
