chore: always push a new image after merging on main (cloudnative-pg#2850)

NiccoloFei · gbartolini · web-flow · commit ab0d5bc09c4a · 2023-09-26T22:37:57.000-03:00
The continuous-integration was only actually pushing images when a PR was 
labeled with "always push images", but we should also produce the images whenever 
a new commit is pushed on main or a release branch.
This will ensure that the `ghcr.io/cloudnative-pg/cloudnative-pg-testing` main and release-*
images are updated as soon as a new commit is pushed (up until now it was done only
once per day via the continuous-delivery workflow)
