ci: drop the Eve getting-started job; Eve is deprecated and its repo no longer resolves

cultmesh-portability's getting-started job checked out GameCult/Eve (404 on the forge) and
ran verify-eve-getting-started.ps1 -EveRoot ./Eve, which is Eve end to end. Nothing in it
runs without Eve, so the job goes. reactive-and-resource-lifetime has no Eve dependency
and is unchanged.
