fix: replace lambdainternal client with botocore lib having latest Lambda client model

- Remove load_preview_botocore_models() calls from initialize_from_env()
- Update boto3.client() calls from lambdainternal to lambda
- Remove lambdainternal botocore model files
- Add boto3/botocore wheel files to lib directory
- Update tests to expect lambda client instead of lambdainternal
- Add allow-direct-references = true to pyproject.toml
