Update Dummy Blueprint version to 0.5

[WeiXiaoBlueRabbit]

This version seems to be outdated. Would you like to update it to version 0.5? Alternatively, could you guide me on how to build it myself?

I made a tool to export dummy assets, but it's very much incomplete and difficult to use. When I have the time, I'll do some refactoring, push the tool to github and then also update the dummy blueprints.
