update: Add criteria to VPN Services page and update other sections (#2788)

Updates include:
- Obfuscation info, ProtonVPN IPv6 and added missing download links
- added a few criteria

Testing:
- Proton has IPv6 support on Linux but it didn't work for me
- Requirements for FDE/ram servers make sense to prevent logging by malicious employees.
- Mullvad/IVPN are ram-only while Proton has FDE.
- Requirements for the jurisdiction is to prevent cases like RiseupVPN (https://riseup.net/en/about-us/press/canary-statement).

     Brave allows you to select additional content filters within the **Content Filtering** menu or the internal `brave://adblock` page. We advise against using this feature; instead, keep the default filter lists. Using extra lists will make you stand out from other Brave users and may also increase attack surface if there is an exploit in Brave and a malicious rule is added to one of the lists you use.
