Enable the LTI error option in the LTI codemod
Enable the LTI error option in the LTI codemod

Summary:
Previously, the LTI codemod needed to have the
`experimental.enforce_local_inference_annotations` option set to true in a
`.flowconfig` for the codemod to find the error locations and add annotations.
I found out that this option can just be set in the codemod itself.
