Missing /home/runner/.local/bin to /etc/environment PATH in ubuntu 22.04

Checks

• 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

Yes, my bug doesn't relate to this component.

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)

Resource Definitions

N/A the problem is not related to Kubernetes

To Reproduce

docker run -it --rm docker.io/summerwind/actions-runner:v2.303.0-ubuntu-22.04 "cat /etc/environment"
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
ImageOS=ubuntu22

Describe the bug

The ubuntu 20.04 image PATH includes /home/runner/.local/bon and so does the Github-hosted ubuntu-latest runner.
I think this is a regression that should be fixed.

Describe the expected behavior

docker run -it --rm docker.io/summerwind/actions-runner:v2.303.x-ubuntu-22.04 "cat /etc/environment"
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/runner/.local/bin
ImageOS=ubuntu22

Additional Context

No response

Start with the Docker image used by docker.io/summerwind/actions-runner:v2.303.0-ubuntu-22.04 and reproduce the issue by reading /etc/environment. Compare its PATH with the Ubuntu 20.04 image and the expected value in the issue. Done means the Ubuntu 22.04 image includes /home/runner/.local/bin in /etc/environment.
