Fix sentry-config typecheck: explicit types: [node] in tsconfig

@types/node is a devDependency of the package but tsc only auto-picks
it up locally due to root node_modules hoisting. CI runs with pnpm's
isolated resolution so the dep isn't visible to tsc without an
explicit types field — matching what packages/jobs/tsconfig.json does.
