[feature] Help new users find out about tools.microsoft.msbuild:vs_version

### What is your suggestion?

I'm trying to use Conan (2.0.14) on the build server, which has VIsual Studio 2022 installed together with build tools for several previous versions as well. I'd like to compile using the 2017 build tools and the 2022 visual studio. My problem is easily solved by the tools.microsoft.msbuild:vs_version setting. But I had to look through the source code to find that out.

1. My default profile didn't contain the setting. Please see [Issue 14487](https://github.com/conan-io/conan/issues/14487). I guess that code change still doesn't generate the setting "out of the box".
2. There is no documentation (that I could find) on the website about this use-case. That would have really helped me to get started with Conan.
