v0.25.0

The highlight of this release is a new Kubernetes container mode that improves the security posture of runner pods by removing the need for privileged containers.

In addition to that, this release improves the reliability of the webhook-based autoscaler, and removes the support for the legacy --once actions runner flag.

The release note covers all the details and you should definitely read it before upgrading! Find it at https://github.com/actions-runner-controller/actions-runner-controller/blob/master/docs/releasenotes/0.25.md.

Lastly, there are also a lot of enhancements, improvements, fixes, and so on for the documentation and the chart. Big kudos to everyone who contributed! Read on for all the changes.
