chore: enable manual run of nightly builds with possibility of skipping tests (#712)

* Add manual dispatch trigger for nightly build workflow, with an input parameter for optionally skipping the e2e and helm tests part of the workflow

* Bump how much memory to start minikube cluster with on e2e test workflows

* Log events from default namespace on tests failure, bump the limit of kubernetes events logged to 30

* Bump workflow-job plugin version used by default from 2.42 to 1145.v7f2433caa07f
