Issue Description:
I would like to request the inclusion of a compatibility matrix in the README.md file of the node-problem-detector repository. The compatibility matrix would provide users with a clear overview of the Kubernetes versions supported by the tool.

A compatibility matrix is essential for users to quickly determine whether the node-problem-detector is compatible with their specific Kubernetes version, thus ensuring a smooth integration and usage experience.

An excellent example of a compatibility matrix can be found in the metrics-server repository's README.md file, specifically at this location: https://github.com/kubernetes-sigs/metrics-server#compatibility-matrix. This matrix serves as a useful reference for users to understand the supported Kubernetes versions by the metrics-server tool.

By including a compatibility matrix in the README.md file of the node-problem-detector repository, users would greatly benefit from the clear and concise information regarding the supported Kubernetes versions.

Thank you for considering this feature request. Please let me know if any additional information is required.
