Program codegen generates invalid TypeScript lambdas.

[iwahbe]

The aws-eks-pp TypeScript test fails with parsing errors. We emitted zones.names.map((k, v) => {key: k, value: v}) which is invalid. We should have emitted zones.names.map((k, v) => ({key: k, value: v}))

Steps to reproduce

1. cd pkg/codegen/internal/test/testdata/aws-eks-pp
2. yarn run tsc --noEmit aws-eks.ts

Expected: Clean compile
Actual:

yarn run v1.22.11
warning package.json: No license field
$ /Users/ianwahbe/Projects/pulumi/pulumi/pkg/codegen/internal/test/testdata/aws-eks-pp/node_modules/.bin/tsc --noEmit aws-eks.ts
aws-eks.ts(34,65): error TS1005: ';' expected.
aws-eks.ts(47,65): error TS1005: ';' expected.
error Command failed with exit code 1.

Note: there are probably other errors behind this test. We can file file issues for those when this test is solved.
