[FLAG-1012] Update privacy policy language

[SARodrigues]

Overview

This PR updates the Privacy Policy text in order to match the updated copy/version in the main WRI website, as per task's description.

Notes:
I made a couple quick changes, unrequested, under review by the QA team:

• I've noticed WRI's Privacy Policy often mentions other sections, which are linked to the respective section via hash tags. This was not working nor implemented at all in the GFW website; I took the liberty of implementing it (no animations, just making them work. If necessary, we can animate the scroll later on)
• Verified that all links have rel="noopener noreferrer"
  Some were missing it. noopener ends up being redundant in this context, but as standard practice I've added both anyways.
• While going through the Privacy Policy, I noticed it was both pretty much unstyled but also extremely difficult to read. I took the liberty of adding a couple styling tweaks, very basic just to improve spacing and readability, mostly focused on:
  • Sized of the headers
  • Spacing of the sections
  • Spacing of the lists
    This doesn't match the ToS, which are also majorly unstyled, waiting from input on the QA team as to whether:
    • Keep the changes
    • Possibly improve ToS spacing as well
    • Revert it (takes a couple minutes)
• There are references to the cookie policy, including a link to open the settings, which works on the main WRI website but doesn't apply here. Waiting on input from the QA team on whether to:
  • Remove the references
  • Reword them to match the GFW cookie system.
