Lyra - Migration from 5.4 to 5.5

@yuri_v_a Did you change something in the default input mapping file IMC_ShooterGame?

I did, and by overwriting the updated Lyra files that file got overwritten aswell. So my custom binding were gone.

I have now created my own IMC file for the plugin I had created for my game to prevent this in the future. I then added the mapping to the LyraExperienceActionSet and now my inputs are working again.
