setup-repos sets wrong repositories

When bootet via netboot from

https://dl-cdn.alpinelinux.org/alpine/v3.17/releases/x86_64/netboot/vmlinuz-lts

with

https://dl-cdn.alpinelinux.org/alpine/v3.17/releases/x86_64/netboot/initramfs-lts

# setup-apkrepos

inserts repository names from edge and not from v3.17 into /etc/apk/repositories
