Include DB type and major and minor version in TARGET_DB name

It should be sqlite-3.45 but Ubuntu may upgrade it before stable release to 3.46

Ah, I see. Maybe then we have to update the comment for SQLite in the .gitlab-ci.yml so the reader knows the version?

Is there an easier way to figure out the major and minor version for each Database type?

I bet there's a way to get version, maybe some meta data but some images are no longer rebuildable as Debian distro evolving

So it will be a trick to align versions and keep them updated, as security releases arriving not only for MySQL/pgsql but for it's dependencies too
