Unexpected preview tagging scheme values for the new 8.0 preview images

[baronfel]

Describe the Bug

The new preview images have a tagging scheme that's out of alignment with the proposal - instead of 8.0-preview.N, images with the 8.0.0-preview.N format are visible on mcr.microsoft.com. I'd like to request retags to fix the version numbers - this mismatch impacts tag inference for the SDK container build tooling.

This was an inaccuracy in the original proposal. It doesn't really provide any value to have both 8.0-preview.N and 8.0.0-preview.N tags because they will always be synonymous. Normally, a two-part version number like 8.0 would be a floating tag that would be updated with each servicing release. But in the context of previews, that doesn't happen. The three-part version number will always be 8.0.0 for each preview release. So 8.0 and 8.0.0 are always equivalent for each preview release.

For that reason, we won't be publishing any 8.0-preview.N tags. We'll get the original proposal updated to reflect this.
