[FE]: Add helm dependency to cert-manager

[damsien]

Roadmap 2025/01 Add helm dependency to cert-manager
As the DevOps of my team, I want to be able to directly build the appropriate final chart to install Syngit on a blank cluster (a new KinD cluster for instance).

What to do

Go to the latest chart version listed. In the Chart.yaml, add the following lines:

  - name: cert-manager
    condition: webhook.certmanager.enable
    repository: https://charts.jetstack.io --force-update
    version: ~v1.16
