[JasonWei512]

Describe the problem

Currently I can't find a way to set the image alignment of MarkdownTextBlock.

The default alignment is "Left".

Describe the solution

Expose an "ImageAlignment" property for MarkdownTextBlock.

<controls:MarkdownTextBlock
    Text="![This is a image](https://image.url)"
    ImageAlignment="Left / Right / Center / Stretch">
</controls:MarkdownTextBlock>
