Moving to Unreal 5

We decided to move Advaria to Unreal 5.

We have done it already with another project - and Unreal 5 is much better at deploying and testing the build.

And our project doesn't use a lot of plugins - and at this time - all of them already working within Unreal 5.

Except for one - Legs IK. But I have found the solution to that already - actually, Unreal 5 already comes in with an example of how to replace it. Fun fact - developer who made that plugin for Unreal 4 was hired by Epic to work on the Unreal 5 IK system.

While we'll migrate Advaria to Unreal 5 - new updates will be not possible. But I hope it will not take much time.
