Operator should not take care of which micro version of images to deploy

It might happen that new fixes on images are released but no change on operator is needed, so we might stand in this condition:

• operator is version X.Y.z
• images are version X.Y.a (where a >= z+1)

Currently, the operator is deploying automatically the images with same full version.Which means, in the above case, it will deploy images X.Y.z. So the new fixes won't be deployed.

For that, we should create a X.Y tag that will be pushed with kogito-images and that is corresponding to the latest micro version of images (here X.Y -> X.Y.a)

and operator can just deploy images with X.Y version, not taking care of which micro version it should deploy.
