[WebToolsE2E][Multiple docs] The "Install .NET Aspire" section in the ".NET Aspire setup and tooling" document should be based on Aspire 9.0.0 instead of Aspire 8.

Describe the issue or suggestion

Issue description
We need to update the instructions in the ".NET Aspire tooling - .NET Aspire | Microsoft Learn" document.

Code Resources: https://github.com/dotnet/docs-aspire/blob/70510f8794568e4a5f1e75b32752cfb50fd6afa3/docs/fundamentals/setup-tooling.md?plain=1#L29C2-L29C99

Issue1:
This version should change to 17.12 instead of 17.9

Issue 2:
VS 17.12 includes Aspire 9.0 templates instead of .NET Aspire SDK by default

Issue 3:
.NET Aspire SDK does not need to be mentioned as a prerequisite because it's a NuGet package.

Issue 4:
A note should be added before this section, such as "If you want to use Aspire 8.2.2, you can install the . NET Aspire SDK according to the steps below"

Hi @davidfowl, we're testing the documentation for aspire 9 GA, shouldn't we update the tutorials in the draft based on current realities?

[davidfowl]

Oh was this using the draft?
