Documentation for primeflex setup

[gotjoshua]

I just spent a little more time than I would have liked importing primeflex into a gridsome project, so i am writing to ask for an extra line or two of documentation about importing primeflex into vue projects.

In the end it was simple:

in main.js:

import 'primeflex/primeflex.css' 

so i suggest adding docs to at least two places:

1. https://primefaces.org/primevue/showcase/#/display ( PR here )
2. https://primefaces.org/primevue/showcase/#/setup ( I am happy to add a P here also, but I need to figure out where...)

Thanks, I've added a separate doc page for PrimeFlex setup in the primeflex submenu. Hope it is more clear now. Should be up live with 2.0.8 later today.
