add rancher-k3s-upgrader 0.5.0

[jiaqiluo]

Issue: rancher/rancher#41511

This PR adds a new version, 0.5.0, for the chart rancher-k3s-upgrader.
Noticeable change between 0.5.0 and 0.4.0 are:

• bump the tag of the image rancher/system-upgrade-controller to v0.11.0
• bump kubeVersion to 1.23 which is the minimum k8s version that Rancher v2.7.0 supports
• fix the value of rancher_min_version. This did not cause any issues because v0.4.0 is available only in rancher 2.7.x

Test

The chart is tested local on a k3s 1.26.4 cluster.

Per offline discussion, we should probably bump the "minor" version of the chart if we are going to be removing K8s version support for older versions.
