Add a landing page for pkgs.k8s.io

[xmudrii]

What would you like to be added:

Relevant to #3317

We should have a landing page at pkgs.k8s.io that shows:

• basic information about the new package repositories
• information about the new package repositories replacing the legacy repositories
• guarantees that we do or don't provide for these repositories

Also see kubernetes/k8s.io#6188 (comment)

Would it be enough to link to an existing or new section/page on https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/#installing-kubeadm-kubelet-and-kubectl ?

@saschagrunert I'd prefer something like registry.k8s.io (https://github.com/kubernetes/registry.k8s.io)

Implemented a temporary workaround to redirect to the announcement blog post in kubernetes/k8s.io#6544
I'll keep this issue open to try to figure out if we can come up with a better landing page

@xmudrii I'd generally prefer integrating the landing page into something we already maintain compared to a separated resource we may forget.

I'm currently trying to upgrade my local labs cluster from v1.29 to v1.30 but I'm facing issues to figure out the correct url for the repository.

After googling and cross reading many blog posts I've found out that prereleases are available using the following repository url for debian/ubuntu:

https://pkgs.k8s.io/core:/prerelease:/v1.30/deb/

A landing page containing information about all releases would be very handy.

I thought about adding a new folder to k/sig-release (e.g. pkgs.k8s.io) that's going to hold the user-facing documentation for the new package repositories, and then we use README in that directory as the landing page. However, before we do that, I'd like to coordinate these efforts with #3317
