Helm charts for ArgoCD (#17)

* chore: Update docker push command and Dockerfile labels
  - Update docker push command in Taskfile.dist.yml to push all tags to the registry.
  - Remove unnecessary labels and update the description in the Dockerfile.
* chore: add Helm chart for Kubernetes deployment
  - Add .helmignore file to specify patterns to ignore during package building.
  - Create Helm Chart files: Chart.yaml, _helpers.tpl, deployment.yaml, secret.yaml, and values.yaml.
  - Define default values for Helm deployment, including replica count, service port, image details, and security context.
* ci(sec): Add codacy config
* feat: Helm charts for Argo
