Summary

Fix three grammar/spelling errors in docstrings and comments under libs/labelbox/src/labelbox/:

• schema/batch.py (Batch.delete docstring): "batches that has labels" → "batches that have labels"
• data/annotation_types/data/raster.py (MaskData docstring example comment): "back ground" → "background"
• data/serialization/ndjson/converter.py (serialize docstring): "Not all edge cases are handling by custom exceptions" → "Not all edge cases are handled by custom exceptions"

Type of change

• Document change (fix typo or modifying any markdown files, code comments or anything in the examples folder only)

No functional changes — comments/documentation only.

Note

Low Risk
Documentation-only edits with no effect on code paths, APIs, or data handling.

Overview
Corrects three grammar/spelling mistakes in Labelbox SDK docstrings and comments only—no runtime behavior changes.

Updates the MaskData example comment (raster.py) from "back ground" to background, fixes subject–verb agreement in Batch.delete (batch.py) to batches that have labels, and fixes passive voice in NDJsonConverter.serialize (converter.py) to edge cases are handled by custom exceptions.
