Increase resources for docker build container

• https://ci.eclipse.org/cbi/view/Jiro/job/jiro-agents/job/master/ => Docker build on static agent takes 6-15 minutes
• https://ci.eclipse.org/cbi/view/Jiro/job/jiro-agents/view/change-requests/job/PR-20/ => Docker build with buildkit takes 28 minutes

added Enhancement label

requested review from @heurtemattes

Last build took 24 min: https://ci.eclipse.org/cbi/view/Jiro/job/jiro-agents/job/master/728/console

Maybe due to azure VM changes.

Anyway, changing containerBuild ressources will have no impact IMO. Builds are running on the buildkit infrastructure. I can try increasing buildkit infrastructure ressources and I see if that changes something.

I just checked and see that limits are quite high: https://github.com/eclipse-cbi/buildkitd-okd/blob/main/buildkitd-privileged.jsonnet#L36

limits: {
       cpu: "4000m",
       memory: "8Gi",
},
