Code Review

This pull request removes the multimodal image and video embedding example files, along with their corresponding unit tests in generative_ai/embeddings/test_embeddings_examples.py. Feedback points out that the unused imports for these deleted modules must also be removed from the top of the test file to prevent a ModuleNotFoundError when running the test suite.
