feat(windows): show nuget download info explicitely in verbose mode (#…

…1449)

# Description

The standard cmake message command prints to `stderr`. So it prints
`Nuget.exe not found, trying to download or use cached version.`, when
building an audioplayers app, which is confusing, as nothing went wrong.
The `STATUS` keyword changes it to `stdout`, which can be accessed via
the `flutter --verbose` command.
Also: 
- updated the `nuget` package to `v6.5.0`
- updated the docs on how to setup Windows and Linux. The paths could
change again, once there are individual READMEs for each platform.

Closes #1303

 In order to install this package, add the [latest version](pub.dev/packages/audioplayers) of `audioplayers` to your `pubspec.yaml` file. This packages uses [the Federated Plugin](https://docs.flutter.dev/development/packages-and-plugins/developing-packages) guidelines to support multiple platforms, so it should just work on all supported platforms your app is built for without any extra configuration. You should not need to add the `audioplayers_*` packages directly.

 1. If the problem still persists, and no existing (open or closed) issue on this repo, no stack overflow question or existing discord discussion solves you problem, then you can open an issue. But you must follow the issue template, and refer to the problem on the example app (or start with its code and make only the necessary modifications to trigger the issue), not on your own app that we don't have access (because since step 2 the error must be reproducible on the example app).
