Partial fix for: #64

@sgallag-insta looks like this can be reverted now? https://copr.fedorainfracloud.org/coprs/ublue-os/staging/build/8160678/

@qoijjj Per my comment here, I think the build was actually always correct. For some reason the repo we are adding is giving us the wrong version. I suspect there's a problem with the URL (maybe OS_VERSION is doing something funky?)

@sgallag-insta I'm confused then, isn't our repo configuration identical to bluefin's? It would be good to get to the bottom of this

@qoijjj I've spent a bit more time looking into this and I too am really confused. I can confirm that the latest build does have the correct file and we seem to be calling the correct URL but when we try to install it from the ublue staging repo it isn't getting the latest (even though the repo seems to contain the latest build).

Also while bluefin's install process is different, I haven't noticed anything we need to do differently
