What type of PR is this?

/kind feature

What this PR does / why we need it:

  • Add support for Kubernetes 1.33.1
  • Add checksum entries of Kubernetes 1.33.1
  • Set min required version to Kubernetes 1.31.x (Drop 1.30.x)
  • Update supported versions
    • cri-o 1.33.0
    • etcd 3.5.21
    • coredns 1.12.0
  • Refactor coredns_version
  • Remove 'AppArmor' feature gate from hardening config because it is removed from kubernetes 1.33
  • Use ubuntu 22.04 instead of 20.04 to test cri-o 1.33.0

Which issue(s) this PR fixes:
Fixes #12162

Special notes for your reviewer:

  • This should be merged after the release of kubespray 2.28.0.
  • Upgrade CI test (ubuntu22-calico-all-in-one-upgrade) will fail until kubespray 2.28.0 is released.
  • The cri-o 1.33.0 (crun 1.21) does not work on Ubuntu 20.04, so we need to remove Ubuntu 20.04 support.

Does this PR introduce a user-facing change?:

Support kubernetes v1.33.1
