📝 Walkthrough

Walkthrough

This PR fixes typos across three files: correcting "defauting" to "defaulting" in docstrings across multiple writer classes in monai/data/image_writer.py, and fixing "transfrom" to "transform" in test comments in tests/data/test_cachedataset.py and tests/data/test_smartcachedataset.py. All changes are cosmetic with no functional impact.
