Update faiss_index_bq_dataset.py

[farzanekram07]

1. Update the import statements: Since the code is using Python 3.7, it's better to use relative imports instead of absolute imports. Replace the import statements like from apache_beam.options.pipeline_options import PipelineOptions with from .apache_beam.options.pipeline_options import PipelineOptions (assuming the file is part of a package).

2. Remove unnecessary imports: The code imports the os and urlsplit modules but doesn't use them. You can safely remove those import statements.

3. Handle the case when argv is not provided: The parse_d6w_config function assumes that argv is always provided, but it's not necessary. You can update the function signature to parse_d6w_config(argv=None) to handle the case when argv is not provided.

4. Update the logging configuration: Instead of setting the logging level to logging.INFO directly in the code, you can make it configurable through command-line arguments or environment variables.

Please don't use "add file"/"update file"/"fix file"/etc. commit messages. These are hard to reason about when looking at the history of the file/repository. Instead, please write explanatory git commit messages.

The commit message is also the title of the PR if the PR has only one commit. It is thus twice important to have commit messages that are relevant, as PRs would be easier to understand and easier to analyze in search results.

For how to write good quality git commit messages, please consult https://cbea.ms/git-commit/
