Remove dead projectcalico.org "Everything you need to know" video links

Meysam flagged that the "Additional resources" links on the Kubernetes
networking training pages no longer play their videos. The linked
projectcalico.org blog pages are dead, so remove the links from all
locations (current and versioned docs) across Calico, Calico Enterprise,
and Calico Cloud.

Covers both link forms:
- "Video:" bullets in Additional resources / Next steps / Recommended
  lists
- inline "in this short video" sentences in determine-best-networking

Where an Additional resources section contained only these video links
(the about-kubernetes-ingress pages), the now-empty heading is removed
too. Unrelated "Blog:" links and the Kubernetes.io references are kept.
