Unable to load shared library 'libSkiaSharp' or one of its dependencies - azure app service on Linux

Description

Just like the bug that was closed #1312 . Except this one is not using any other external libs, it’s just the Skia code.

A page that accesses Skia on Azure Linux fails. The same page on Windows desktop or Azure runs fine.

This also solved my issue, allowing Maui.Graphics tests to run on Linux in GitHub Actions 👍 🚀

<PackageReference Include="Microsoft.Maui.Graphics" Version="6.0.101-preview.9.512" />

Previously my error was:

I managed to get the dll using this package “HarfBuzzSharp.NativeAssets.Linux” Version=“2.8.2.1-preview.79”

Thanks for the hint @marciosarabando, installing the package “HarfBuzzSharp.NativeAssets.Linux” solved it for me as well (.NET 6 running on Raspberry Pi Linux).
