CHORE: Bump capi images

[AlexCK-STFC]

• Add 1.35 and 1.36
• Bump minors for 1.33 and 1.34 (others are fine)
• Bump submodule
• Bump ansible core

Tested 1.35, briefly, on CAPI. Cluster deployed successfully. Not done in depth testing.
But azimuth are using them both so they're prob fine

Also, this script might be worth adding to the readme:

printf "%-20s %-20s %-25s\n" "kubernetes_series" "kubernetes_semver" "kubernetes_deb_version"
printf "%-20s %-20s %-25s\n" "-------------------" "-------------------" "------------------------"

for v in v1.31 v1.32 v1.33 v1.34 v1.35 v1.36; do
 deb_version=$(
    curl -fsSL "https://pkgs.k8s.io/core:/stable:/$v/deb/Packages" |
    awk '
      /^Package: kubeadm$/ {found=1}
      found && /^Version:/ {print $2; found=0}
    ' |
    sort -V |
    tail -1
  )

 semver=$(echo "$deb_version" | sed -E 's/^([0-9]+\.[0-9]+\.[0-9]+).*/\1/')

 printf "%-20s %-20s %-25s\n" "$v" "v$semver" "$deb_version"
done
