Test: HTML meta tag CSP Blocking Fonts

Originally from https://github.com/playwright-karthik/qatesting/blob/d96c70395c9401622adb2ff1b7556415d5a254f7/blockcsp.html but I wanted a copy.

This page tries to load the Roboto font from Google Fonts. Due to the HTML meta tag CSP rule font-src 'none', it should be blocked.

Open your browser's DevTools → Console or Network tab to verify the font request is blocked.
