Calico KDD requirement is actually missing from the MKE3 to MKE4 Upgrade page

[sergeymirantis]

Dear team,

We need to be more clear on requirements for Calico backend for the upgrade. @vikramhh I presume that KDD is still a requirement in 4.0.0?

@sergeymirantis - KDD is a requirement for upgrading an MKE3 cluster to MKE4

Thanks @vikramhh - it's not highlighted in the docs. can we please fix it?
would you be so kind to write a note or give @KoryKessel-Mirantis guidance on it?

Thank you both!
