Document the SkiaSharp imaging provider

Update the image-manipulation reference to list SkiaSharp alongside
ImageSharp and Magick.NET, and add a SkiaSharp Provider section with
installation steps and the SkiaSharpResizerOptions /
SkiaSharpCompressOptions configuration knobs.

 # Image Manipulation
-ABP provides services to compress and resize images and implements these services with popular [ImageSharp](https://sixlabors.com/products/imagesharp/) and [Magick.NET](https://github.com/dlemstra/Magick.NET) libraries. You can use these services in your reusable modules, libraries and applications, so you don't depend on a specific imaging library.

+## SkiaSharp Provider
+
+`Volo.Abp.Imaging.SkiaSharp` NuGet package implements the image operations using the [SkiaSharp](https://github.com/mono/SkiaSharp) library.
+
+## Installation
+
+You can add this package to your application by either using the [ABP CLI](../../cli) or manually installing it. Using the [ABP CLI](../../cli) is the recommended approach.
+
+### Using the ABP CLI
+
+Open a command line terminal in the folder of your project (.csproj file) and type the following command:
+
+```bash
+abp add-package Volo.Abp.Imaging.SkiaSharp
+```
+
+### Manual Installation
+
+If you want to manually install;
+
+1. Add the [Volo.Abp.Imaging.SkiaSharp](https://www.nuget.org/packages/Volo.Abp.Imaging.SkiaSharp) NuGet package to your project:
+
+```
+dotnet add package Volo.Abp.Imaging.SkiaSharp
+```
+
+2. Add `AbpImagingSkiaSharpModule` to your [module](../architecture/modularity/basics.md)'s dependency list:
+
+```csharp
+[DependsOn(typeof(AbpImagingSkiaSharpModule))]
+public class MyModule : AbpModule
+{
+    //...
+}
+```
+
+### Configuration
+
+`SkiaSharpResizerOptions` is an [options object](../fundamentals/options.md) that is used to configure the SkiaSharp image resize system. It has the following properties:
+
+* `SKSamplingOptions`: The sampling options used by SkiaSharp when resizing. (Default: `SKSamplingOptions.Default`)
+* `Quality`: The quality of the encoded image (0-100). (Default: `75`)
+
+`SkiaSharpCompressOptions` is an [options object](../fundamentals/options.md) that is used to configure the SkiaSharp image compression system. It has the following properties:
+
+* `Quality`: The quality of the encoded image (0-100). (Default: `75`)
+
+**Example usage:**
+
+```csharp
+Configure<SkiaSharpResizerOptions>(options =>
+{
+    options.Quality = 80;
+});
+
+Configure<SkiaSharpCompressOptions>(options =>
+{
+    options.Quality = 60;
+});
+```
+
 ## ASP.NET Core Integration
 
 `Volo.Abp.Imaging.AspNetCore` NuGet package defines attributes for controller actions that can automatically compress and/or resize uploaded files.
