Source code not showing on non-Windows build targets

[Arlodotexe]

Background

As part of #29, we are now able to pull in and show in source code for each sample, bundled as app content and pulled in via StorageFile.GetFileFromApplicationUriAsync().

However, due to a bug with Uno (filed separately here), we're unable to pull in and view the source code on any platform other than UWP and WinAppSDK.

Solution(s)

Either unoplatform/uno#8266 (see unoplatform/uno#2502 (comment)) needs to be solved, or a workaround needs to be created.

Or, as a temporary workaround, create a custom MSBuild Target that

• Checks the head for all referenced projects
• Checks each referenced project for any usages of
• Manually copy the files to the project head's "Assets" folder

Then, modify all of our code to only use the Assets folder.
