Doc Enhancement: Image Cropper \ Blazorise extend documentation for MaximumReceiveMessageSize

[njannink]

We are migrating from Blazor Wasm to Blazor Server and I spend the entire morning trying to figure out why the cropper isn't working.

In the end the problem was with the maximum blazor message size:

        .AddHubOptions(o =>
        {
            o.MaximumReceiveMessageSize = 1024 * 1024 * 100;
        })

Might be good to clarity this in the Blazorise documentation of the image cropper and getting started
