Add note on the .NET CLI default launch profile

[guardrex]

Fixes #37204

Thanks @cremor! 🚀

Tom, Wade ... Just need one review to get this in.

I place a NOTE in an INCLUDES file for this one because I'd like to use it in several Blazor node articles. For the main doc set's Environments article, I update the ms.date.

If you feel that we should place this as normal text, I'll strip the NOTE designation, leaving this content as a paragraph in the INCLUDES file. It could go either way. NOTEs do break up the flow of the text. I'm on the fence about it. 😄

BTW ... I disagreed with Copilot's recommendation on the structure of the last sentence of the INCLUDES file. It prefers two assumed "you" imperative tense subjects ("[you] pass ... , or [you] move ..."), but I prefer one subject. So, I went with the sentence structure "[you] pass ... or move ..." without a comma.

Pull request overview

This PR documents which launchSettings.json launch profile the .NET CLI uses by default (when dotnet run/dotnet watch is executed without specifying a launch profile), and reuses the guidance across multiple ASP.NET Core and Blazor articles via a shared include.

Changes:

• Adds a reusable include explaining the default .NET CLI launch profile behavior and how to select a different profile.
• Updates the main ASP.NET Core Environments article to reference the new include and refreshes ms.date.
• Replaces/augments existing Blazor guidance with the shared include across several articles.
