RPI Imager repo links for nightlies don't distinguish bit versions

[Taomyn]

Was hoping to try this some time this week, so I tried to use the RPi imager to grab the latest, but it's a bit confusing as to which 64bit one is which as some are duplicated:

I'm using the Windows imager with the command: "C:\Program Files (x86)\Raspberry Pi Imager\rpi-imager.exe" --repo https://octopi.gnethomelinux.com/rpi-imager/rpi-imager-octopi.json the same happens with the mirror link.

Thanks for pointing out will look in to it.

The issue is because the ending was added in the variant here:
https://github.com/guysoft/OctoPi/blob/devel/src/variants/rpios_arm64/config#L8

But now OctoPi uses CustomPiOS v2 which uses the base board system and not a variant to build base64:

https://github.com/guysoft/CustomPiOS/blob/devel/src/images.yml#L7

Need to think if there is an elegant way to add this to the broad configuration

I could also just append it based on the folder or store somehow the base board path in my ci:
https://github.com/guysoft/unofficialpi/blob/ci/src/create_rpi-imager-distro.py#L62

Ok according to the internal sourcing diagram I should be able to just inject the architecture in to the distro name because its already sourced, will test that:
