Promoting aarch64 Workstation to /pub/fedora/linux/

[Mohan Boddu]

Hi all,

Currently aarch64 Workstation is considered a secondary arch
deliverable and synced to /pub/fedora-secondary/ but with aarch64
Workstation being release blocking [1], we are moving it to
/pub/fedora/.

It will increase the space of /pub/fedora/ by 3G.

Thanks,
Mohan Boddu.
