make ci lint/install run based on paths

Instead of using chart-releaser heuristics, use GitHub actions to trigger the action. This cuts down on GitHub Action churn to "check for changes" and ensures tests run when action definitions change. This is particularly efficient because there is only one chart in this repository (i.e. no benefits gained from chart-releaser being selective)
