docs: fix - web-components.min.js must be added for Windows Forms/BlazorWebView/RCL combination

[hml-coder]

🙋 Documentation Request

The documentation is not accurate for a Windows Forms project (net7.0-windows) that hosts a razor component -- from an RCL -- in a BlazorWebView.

"The hart [sic] of this library is formed by the Fluent UI Web Components and the accompanying web-components.min.js file. From version 2.3 onwards, the script is included in the library itself and no longer needs to be added to your index.html or _Layout.cshtml. In fact, doing this might lead to unpredictable results."

💁 Possible Solution

A reference to the web-components.min.js file must be included in the wwwroot/index.html file of a Windows Forms project when hosting Razor components from a Razor Component Library (RCL) in a BlazorWebView. If the javascript file is not included, the FluentUI styling is not applied.

<script type="module" src="_content/Microsoft.Fast.Components.FluentUI/js/web-components.min.js"></script>

Tested 2.3.*, 2.4.1, 2.4.2 and 3.0.0-RC.1

Styles are not applied for 2.4.2 whether web-components.min.js is included or not.

However, styles are applied to FluentUI 2.4.2 when web-components-v2.5.16.min.js is included, but styles will no longer load for 2.3.*, 2.4.1 and 3.0.0-RC.1.

<script type="module" src="_content/Microsoft.Fast.Components.FluentUI/js/web-components-v2.5.16.min.js"></script>

See #633 (comment) on why the script is not being included automatically

On the web-components script file...

Starting with version 2.4.2, we added a version part to the (automatically loaded) web components script. So it will show up, in DevTools for example
<script type="module" src="_content/Microsoft.Fast.Components.FluentUI/js/web-components-v2.5.16.min.js"></script>
Versions before will still have
<script type="module" src="_content/Microsoft.Fast.Components.FluentUI/js/web-components.min.js"></script>

In v3 we will also add this version part to the script BUT that has not been done yet for the RC1 version/package. Any newer versions will have the version appended.

Hope this clears up some confusion..,
