Fix failing to load data/db/index file on non-Win desktop platforms

[Jklawreszuk]

PR Details

Description

On Linux, on creating simple empty window app by simply calling Game.Run(), Stride will throw FileNotFoundException: Could not find file myproj/net6.0/data/db/index. This bug should also appear on macOS in the same way.

I have now extended setting isReadOnly variable to false for all desktop platforms, so that the index file doesn't have to be created manually. Tested on Fedora 38, Windows 10.

I had the same issue with Linux code only. I had to copy that file manually from Windows 🤣

I always created the file manually and it worked too. This isn't invasive change and will make running the game less annoying 😃
