fix(e2e): Add node types to generic TS test tsconfigs

With types:[], @types/node was only loaded because @types/pg
(transitive dep of instrumentation-pg) had `/// <reference types="node" />`.
Removing instrumentation-pg broke that chain. Explicitly including
"node" in types reflects what any real Node.js consumer would have.
