Pre-build ES-DE

As we do with MAME

I have started to look at creating a workflow file for ES-DE as an appimage that auto builds

I now have ES-DE building as an image. Slight change to the build to file to executable

https://github.com/The-Galaxian/RetroDECK-ES-DE/actions/runs/9677966472

ES-DE have a separate build for the SteamDeck which I could also replicate.

IS using an Appimage for this project within RD worth looking into further?

Or stay with full Flatpak build?

Even this could be replicated as a workflow to help reduce build time for RD using SHAs and placeholders?
