fix: Windows runner 'node_modules' is not recognized as an internal or external command

[EdgarsGarsneks]

Summary

Fix proposal for Windows runner 'node_modules' is not recognized as an internal or external command issue resolving #78.

Here is workflow run that executed all os on fork. I was lazy to fix github secret step because of that all jobs fail, but they do execute build and lint successfully, which I hope should be enough evidence 😄

Details

• Instead of executing ng build and lint by path node_modules/.bin/ng use npx npx ng instead that does not rely on path.
• Update workflow to test action also on windows and macos
