(dev-v2.6-archive) Fix alerting-drivers Chart.yaml

This is required due to the change released in v0.1.0 of the charts-build-scripts to switch the package used for YAML marshalling / unmarshalling.

Note: This does not need a packageVersion bump since it has already been bumped once for this release.
