chore(chart): add helm.sh/images to chart.yaml file, update Renovate image ref

General MR

Summary

• This MR adds the registry1.dso.mil haproxy image to the Chart.yaml file under .annotations.helm.sh/images, so this haproxy repository maintains consistency with our other charts.
• This MR is also updating the renovate.json to reference the v2.4 version of haproxy so Renovate can pick up the new dependency updates.

Note:

• Although this package is moving towards "deprecation," the linked issue was recently created to maintain consistency while it is still available and maintained.
