3. Please describe how your code solves the related issue. The solution involves integrating the query_tag parameter into the session_parameters dictionary. This dictionary is part of the connection arguments used when establishing a connection to Snowflake through SQLAlchemy. By including query_tag in session_parameters, users can specify a custom query tag to be associated with their queries.

If the user does not explicitly provide a query_tag, the library will revert to its current behavior. In this case, no query tag will be attached to the executed queries. This ensures backward compatibility with existing codebases and prevents any unintended changes in behavior for users who do not wish to utilize the query_tag functionality.

If the user provides a query_tag in the session_parameters dictionary, the library will extract it and set it in the queries being executed against Snowflake. This allows users to dynamically specify custom query tags based on their requirements.
