bug: quickget thinks Fedora Workstation doesn't support arm64

**I confirm this bug has not already been reported** - [x] I have searched the issues and this bug has not been reported previously **Describe the bug** When trying to install Fedora Workstation on an arm64 machine, it fails. The error message, `ERROR! Fedora Workstation is not available for arm64 architecture.`. **To Reproduce** Steps to reproduce the behaviour: 1. Run `quickget fedora 43 Workstation`. I'm running this on an M1 Macbook Pro, which is `arm64`. Running the command with `--arch arm64` didn't change the results. `quickreport` wasn't an available command. I am running: - macOS v15.7.3 - Macbook Pro M1 - quickget/emu installed via Homebrew - QuickEmu v4.9.9 --- I checked the Fedora website and it looks like arm64 for Fedora Workstation exists and has for a long time. If someone doesn't quickly know the issue & fix for this, I can take a look at the code. It seems like arm64 is a recent feature of this project (https://github.com/quickemu-project/quickemu/pull/1820) so perhaps this is simply somewhere in the code where amd64 was assumed when it shouldn't have been.
