Enhance Query Input with Autocomplete (#930)

Adding Autocomplete feature to Query Input. Query bar provides helpful suggestions as you type and guides in building queries without needing to memorize specific attribute names. Leads to fewer errors and makes the process of filtering workflows quicker and efficient. Performed local testing using development environment, ensuring styling of component was maintained.
