Add example that sets a render mode programatically

[guardrex]

Description

This is a second example, and it's better for a new section on render mode by area. The example can show setting the render mode by path ...

<Routes @rendermode="@RenderModeForPage" />

...

[CascadingParameter]
private HttpContext HttpContext { get; set; } = default!;

private IComponentRenderMode? RenderModeForPage => 
    HttpContext.Request.Path.StartsWithSegments("/Admin") ? InteractiveServer : null;
