Images no longer render in Preview 13

[mobycorp]

Description

I have ensured that all of the .svg files are have a build type of MauiIcon per the documentation on Images, yet they do not show up. I also tried to set all image files to have a build type of MauiImage to no avail.

Here is a screen shot from Preview 12. Notice the icon in the flyout head and all of the flyout item icons are drawn correctly.

Here is the same page in Preview 13.

Something is also going on with the flyout header margin (I have it set to 0,-40,0,0 so that it will align with the header row, but I need to do some more digging on that. Right now, I'm more concerned about the images not being drawn...

Steps to Reproduce

1. Create new .NET Maui app
2. Run the app (with no changes)
3. It complains about the splash screen icon not being found (so I simply commented it out in the Platforms\Windows\Package.appxmanifest file - this too is a bug which I will file separately)
4. Notice the dotnet_bot image does not appear.

I can confirm this bug - I just upgraded my environment and project from Preview 12 to 13.

It may be worth noting, that images drawn from memory streams (created e.g.; using ImageSource.FromStream()) render just fine.

From your screenshot I see its a windows app, this might help: https://github.com/dotnet/maui/wiki/Migrating-to-Preview-13

As I indicated in issue #4736, I discovered an element in the header of App.xaml that was pointing to Assets as the image directory. Namely, windows:Application.ImageDirectory="Assets" I bumble-stumbled upon that when I was looking at something else. When I removed that line, images started to appear!

I will not close this issue. I will let @jsuarezruiz close it so that he knows how I resolved the issue.

Since that platform-specific attribute (windows:Application.ImageDirectory="Assets") needs to be removed from App.xaml, that also needs to be mentioned in the migration guide.

Since I removed it in an attempt to resolve the build error even before finding the migration link, couldn't recall it while adding this #4736 (comment).

@egvijayanand it's now added to the migration guide, glad this was figured out! 🐳
