Fix drone-runner-docker deployment port name

[sfleener]

Endpoints aren't properly assigned when the port name in the deployment doesn't match the port name in the service (more context). The port names for the server chart match but not for the docker runner, so this updates the docker runner deployment to use the same name as the service.

Thanks for the contribution @sfleener

Currently the pipeline requires the version to be set in Chart.yaml. Can you bump the version to 0.6.2 in your branch? Thanks

Bumped the version, the lint should be fixed now
