Documentation: Consider adding community release tracker to Resources

[jpgraphicnexus]

What would you like to be added:

A link to ReleaseRun (https://releaserun.com/kubernetes-releases/) in the community resources section as a release tracking tool.

Why is this needed:

It provides a continuously updated timeline of Kubernetes releases with:

• Version history since early releases
• Direct links to official release notes
• Helpful for teams planning upgrades

Additional context:

The site updates automatically daily and is designed to complement (not replace) the official release pages by providing a historical timeline view, with how to guides as well.

Happy to submit a PR to the appropriate docs page if helpful.

This issue is currently awaiting triage.

SIG Docs takes a lead on issue triage for this website, but any Kubernetes member can accept issues by applying the triage/accepted label.

The triage/accepted label can be added by org members by writing /triage accepted in a comment.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

If we want that page to have more information on it, pull requests are welcome.
I don't think we would hyperlink to https://releaserun.com/kubernetes-releases/
