Add 1.X-debian-stable type alias

[Jorropo]

Hey I am maintaining some software and I recently noticed that some of our docker images were built with the wrong version of go (1.19.10 when 1.19.12 was the latest on the 1.19 branch at the time).
AFAIT this is because buster was no longer supported and you switched to bullseye and bookworm instead.
So I should have used 1.19-bulleyes or 1.19-bookworm images, however our docker deployment is automated and we only really look at it when bumping the major go version (we don't do that automatically due to regressions in the go std ipfs/kubo#10065)

As a maintainer that rely on your work it would make my life easier if you could provide an alias along the lines of 1.X-debian-stable where X is 20 or 21 to take the current releases of go as example. Exactly like you already do for -alpine.

I guess for consistency the full matrix of precision should also be supported like you do for alpine so:

• 1.X.Z-debian-stable
• 1.X-debian-stable
• 1-debian-stable
• debian-stable

But I personally don't need it.

I'm not sure about -debian-stable, -debian or something else could very well be a better name.

Thx 🙂

Debian is the default variant and the current stable (bookworm) is the default release. So we already have 1.21.0, 1.21, 1, latest and 1.20.7, 1.20 tag sets to choose the newest stable Debian with go 1.21 (or 1 or 1.20).

I see, I missed the Shared Tags section.

Technically debian stable and bookworm are different (stable use a different sources.list which implicitly rolls to the next debian stable release) but I don't need it in my case.

Thx

I like to use the analogy of a "square wheel" in relation to the way debian:stable "rolls" 😄 (a vehicle with square wheels is not going to be a smooth ride 🙈)
