- I've already read https://github.com/actions/actions-runner-controller/blob/master/TROUBLESHOOTING.md and I'm sure my issue is not covered in the troubleshooting guide.
- I'm not using a custom entrypoint in my runner image
Checks
- This isn't a question or user support case (For Q&A and community support, go to Discussions. It might also be a good idea to contract with any of contributors and maintainers if your business is so critical and therefore you need priority support
- I've read releasenotes before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes
- My actions-runner-controller version (v0.x.y) does support the feature
- I've already upgraded ARC (including the CRDs, see charts/actions-runner-controller/docs/UPGRADING.md for details) to the latest and it didn't fix the issue
- I've migrated to the workflow job webhook event (if you using webhook driven scaling)
To Reproduce
1. Go to https://hub.docker.com/r/summerwind/actions-runner/tags
2. Compare summerwind/actions-runner:latest with the latest ubuntu 20.04
3. They are the same, which should not be the case

Describe the bug
Hello,
The docker image summerwind/actions-runner
with the tag :latest
grabs ubuntu 20.04, instead of the newer version ubuntu 22.04.
Ubuntu 20.04 is phased out at Github as runner, so this means that github actions start dropping support 20.04. Would be nice if latest actually supports the latest ubuntu versions. Specifically mentioning this, because we will also get Ubuntu 24.04 at some point, so it should favor that one instead once that gets supported over 22.04.
Workaround
If you're facing the same issue, simply pin to ubuntu-22.04
Like this
summerwind/actions-runner:ubuntu-22.04
Describe the expected behavior
Latest should grab ubuntu-22.04
