Adding waitForPodSec var to override in Jenkins helm chart

[mkridi-r7]

Is your feature request related to a problem? Please describe

currently there is no way to override the waitForPodSec without having to pass entire Kubernetes block,

Describe the solution you'd like

having this value added to the helm chart will allow overriding the value like ** containerCap** https://github.com/jenkinsci/helm-charts/blob/main/charts/jenkins/templates/_helpers.tpl#L142

Describe alternatives you've considered

No response

Additional context

some pods take longer than defaulted 600 seconds to start due to the docker image sometimes being very large
