Fixing the nuget problem on CI windows

[molnard]

Constant Red X on windows CI makes devs ignore it and starting to become negligible.

Versions of nuget.exe since 3.4.1 have not auto-included nuget.org as a source. It needs to be included in your nuget.config file (recommended) or added by the DotNetCoreCLI/NuGetCommand task. When you have includeNuGetOrg set to 'true', you should see 'Adding the following sources to the config file: NuGetOrg' in a debug build's log

I made 2 things:

1. Solve the NuGet offline package problems by disabling the cache for packages.
2. Disabled the constantly failing test on windows CI NodeBuildingTests.GetVersionTestsAsync by filtering it out. - will be solved in another PR

This is a hack.

@molnard NodeBuildingTests.GetVersionTestsAsync - this test may fail for a valid reason. I have actually had a look at it a few days ago and there is:

1. WalletWasabi/WalletWasabi/Microservices/ProcessBridge.cs

   Line 84 in eff4a2c

   using var process = Start(arguments, openConsole);

   - starting the process

2. WalletWasabi/WalletWasabi/Extensions/ProcessExtensions.cs

   Line 31 in eff4a2c

   process.EnableRaisingEvents = true;

   - setting EnableRaisingEvents and registering of Exited
   Note that this is after the process is already running so you are not guaranteed that Exited is called (even though it's unlikely) but I don't like it personally.
