[#361] Use the highest dashboard version for deployment traceability

In order to ensure accurate deployment traceability, it is necessary to
use the highest existing version of the Grafana dashboard incremented by
1. This adjustment is crucial as the target instances have intermediate
versions beyond version 35, and leveraging the most current version will
maintain consistency in the deployment process.

Changes:
- Updated the version of the Grafana dashboard to 44 in the
  `govtool.json` file under
  `scripts/govtool/config/templates/grafana-provisioning/dashboards/`. By
  adjusting the version number, we align the dashboard with the latest
  iteration, thereby enhancing traceability and ensuring compatibility
  with the current deployment environment.
