refactor: streamline docstring and error message in bedrock tests

Updated the docstring for the test_bedrock_provider_model_profile_all_geo_prefixes function to be more concise. Modified the error message in the test_latest_bedrock_model_names_geo_prefixes_are_supported function to remove the file path reference, enhancing clarity.
