Nx: Docs: linked stackoverflow tag is wrong

[kiwikern]

The tag [nx] has been split into [nrwl-nx] and [nomachine-nx], see https://meta.stackoverflow.com/q/382809/4694994.

The nrwl website https://nx.dev/ links to https://stackoverflow.com/questions/tagged/angular+nx (on the bottom of the page under Help).

This link should be updated to https://stackoverflow.com/questions/tagged/nrwl-nx
