PCbuild/find_python.bat uses broken aka.ms/nugetclidl URL for downloading nuget.exe

[ELundby45]

Bug report

Bug description:

PCbuild/find_python.bat currently defaults NUGET_URL to:

https://aka.ms/nugetclidl

This appears to no longer resolve to a valid nuget.exe download. As a result, Windows builds that rely on find_python.bat to bootstrap nuget.exe may fail before Python can be installed from NuGet.

Relevant CPython code:

@if "%_Py_NUGET_URL%"=="" (set _Py_NUGET_URL=https://aka.ms/nugetclidl)
@powershell.exe -Command Invoke-WebRequest %_Py_NUGET_URL% -OutFile '%_Py_NUGET%'

Reproducer showing that the url now redirects to bing.com

curl -vI https://aka.ms/nugetclidl

Ideally Microsoft can fix the https://aka.ms/nugetclidl URL, otherwise we should change it.

Let's ask @zooba.

I guess it got cleaned up at some point (fairly recently, I go through that download path often enough that I know it worked earlier this week). There have been a lot of personnel changes at Microsoft recently, so I guess it ended up with no actual owner.

According to https://learn.microsoft.com/en-us/nuget/install-nuget-client-tools?tabs=windows#nugetexe-cli, the URL is https://dist.nuget.org/win-x86-commandline/latest/nuget.exe. This is the page that the aka link came from, so someone was ahead of the breakage.

I can confirm it was working just two days ago.
