Devise an LTS strategy for our Docker Images

[fhennig]

Context: For our 22.11 release we wanted to upgrade base images for our older product images. This raised the question of how far back we should do this and whether we should do it for all images etc.

An outcome of this could also be to keep everything updated for now until we find a reason not to do this anymore.

which are currently under discussion

To move on with this, we need a executive decision on how long we wanna support the different lines mentioned in the ADRs above. There are TODOs for it. @lfrancke @soenkeliebau
