Ubuntu Server Kinetic amd64 and arm64 images aren't downloadable via the provided links

[Aaron Rainbolt]

Steps to reproduce:

1: Open http://iso.qa.ubuntu.com/qatracker.
2: Click "Kinetic Daily".
3: Click "Ubuntu Server amd64" or "Ubuntu Server arm64".
4: Click "Link to the download information".
5: Click the HTTP download link.

Expected result: Ubuntu Server Kinetic amd64 (or arm64) download should trigger.
Actual result: A "Not Found" error appears in the web browser.

Additional info: The Ubuntu Server Kinetic amd64 images appear to be building, but today's link points to http://cdimage.ubuntu.com/ubuntu-server/daily/20220515/kinetic-legacy-server-amd64.iso. The "daily" isn't right - it should be "daily-live", since that's where the images are showing up (as verified by manually messing with the URL until I got somewhere). Alternatively, the "daily-live" directory could be renamed "daily", which would be more accurate, since technically the Ubuntu Server installer isn't a live environment AFAIK.

Also, the Raspberry Pi and riscv64+unmatched images appear to be downloadable.
