Tell us more.

As stated by the documentation at:
https://docs.renovatebot.com/modules/versioning/#debian-versioning

The current debian versioning scheme does not support the <codename>-<date> version format.

However it's already supported by the ubuntu versioning scheme:
https://docs.renovatebot.com/modules/versioning/#ubuntu-versioning

It would be nice to port that feature from ubuntu to debian.
