This PR is for AFTER Helm chart 1.19 release.

closes: #60141

With this all legacy Airflow Version support for below 2.11 is dropped. Minimum Airflow 2.11 version is needed from then on.

Not sure if documentation-related changes we would like to do in a separate PR, but I will list the things which I've found here:

  1. chart/README.md - information regarding supported versions
  2. chart/docs/index.rst - information regarding supported versions
  3. chart/docs/manage-dag-files.rst - section "Mounting Dags using git-sync sidecar without persistence" and "Bake Dags in docker image"
  4. chart/docs/production-guide.rst - section "Kubernetes Secret"
  5. chart/docs/quick-start.rst - section "Extending Airflow Image"

Probably, we would also need a newsfragment for this one

Thansk for the EXTENSIVE / exhaustive review! I think I applied all. Merged current main for better re-reviewability. Let's see if CI is green.
