ci: remove broken --name ${inputs.name} support

[michaelfig]

This PR removes support for the broken inputs.name support, and also removes the CI with.name usage that caused starship stop to attempt deleting a different Helm release name than the one specified in the starship-action's config file.

This will allow starship stop to successfully delete the Helm release. Before, it failed and waited until the Actions job timeout elapses (currently 6h, but also updated in this PR to be just 15 minutes):

Run starship stop --config config.yaml --namespace $NAMESPACE || true
  starship stop --config config.yaml --namespace $NAMESPACE || true
  kubectl delete namespace $NAMESPACE --wait=true
  shell: /usr/bin/bash -e {0}
  env:
    NAMESPACE: ci-hyperweb-io-starship-action-test-refs-heads-main
argv: config : config.yaml
argv: namespace : ci-hyperweb-io-starship-action-test-refs-heads-main
config again: [object Object]
Trying to stop all port-forward, if any....
helm delete osmo-wasm --namespace ci-hyperweb-io-starship-action-test-refs-heads-main
