Fix GoogleGRID url in Clear-Proxy.ps1

[sjawhar]

I found this while trying to debug why my EC2 instances launched from snapshots are always stuck at 1366x768 even though the machine the snapshots were created from works just fine. Didn't fix my problem, but maybe this will fix someone else's.

Two changes:

• URL of Google Cloud support page has changed
• There are now separate links for Windows Server 2016 and 2019, but the 2019 link looks (?) like it should work for both based on the file name

Thanks for your PR, this entire Clear-Proxy script needs a refactor, as it's mostly duplicate code of GPU updater tool + two entirely unrelated functions (removing the user set proxy and expanding the C partition automatically if the disk has been expanded).

These items are mostly there to protect users who don't have RDP access to fix accidentally doing something that breaks Parsec (like uninstalling their GPU or adding a proxy which prevents Parsec's connection). Now everyone has RDP access (because everyone who uses this self hosts their machine)...it makes less sense to even include Clear-Proxy.

GPU updater tool needs a refactor to accept a "-quiet $true" param, which will set it to run without user interaction and then clear-proxy can call that when required (AKA when the user deletes their GPU driver).

Makes sense. I've stopped trying to use this because of the issues I mentioned above and because I haven't been in places lately with fast enough internet to stream anyway :laughing: If you'd like, I can take a look again when I'm back in a land of decent bandwidth.

For now, I have removed the shortcut to this script from the desktop when you set up a new cloud machine. It's not essential to the function of the cloud machine and it will return when it's refactored.
