Ubuntu suffixed Dated Codename versions

What would you like help with?

I think I found a bug

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub

Please tell us more about your question or problem

Recently we noticed that renovate didn't pick up the latest version of Jammy from upstream dockerhub - see: https://hub.docker.com/layers/library/ubuntu/jammy-20240627.1/images/sha256-0eb0f877e1c869a300c442c41120e778db7161419244ee5cbc6fa5f134e74736?context=explore

We use custom versioning for these, as opposed to using renovate ubuntu versioning - and had thought we might have missed an edge case that would be resolved by using the ubuntu versioning.

Looking into the implementation... It looks like we renovate will never pick up an ubuntu version tagged this way either.

ie. https://github.com/renovatebot/renovate/blob/main/lib/modules/versioning/ubuntu/common.ts#L3

The following regex is used, which would never match on jammy-20240627.1 due to the suffixed .1

/^(?<codename>\w+)-(?<date>\d{8})$/

We haven't been able to find details of what exactly this means on the dated codename version so far - but it doesn't look to be a mistake on the part of the maintainers and there are historical releases matching this as well.

Should renovate support matching this also?
