Subject: [PATCH] Fix panic in code generator when generating lambda controller
 (#384)

The recent patch ([PR 383](https://github.com/aws-controllers-k8s/code-generator/pull/383)) introduced a regression that caused the
code generator to panic when generating the lambda controller.
This commit addresses the issue by adding a check to ensure that
the shapeRef reference is not nil before accessing the
Documentation field. This prevents the panic from occurring and
allows the code generator to function correctly.
