chore(lambda): remove commented out unit tests (#35522)

### Issue # (if applicable)

Closes #<issue number here>.

### Reason for this change

During NodeJS changes in PR #35412 I missed removing this code. The same unit tests exist in a [different file](https://github.com/aws/aws-cdk/blob/main/packages/aws-cdk-lib/aws-lambda/test/nodejs-latest-runtime.test.ts), and these need to be removed

### Description of changes

Removing commented-out unit tests.

### Describe any new or updated permissions being added

NA


### Description of how you validated changes

Build
