Evals docs (#7460)
Still don't have good "how to's", and the guides / examples section could be further pruned and improved, but this PR adds a couple examples for each of the common evaluator interfaces. - [x] Example docs for each implemented evaluator - [x] "how to make a custom evalutor" notebook for each low level APIs (comparison, string, agent) - [x] Move docs to modules area - [x] Link to reference docs for more information - [X] Still need to finish the evaluation index page - ~[ ] Don't have good data generation section~ - ~[ ] Don't have good how to section for other common scenarios / FAQs like regression testing, testing over similar inputs to measure sensitivity, etc.~

They both use the SUM function to add up the sale_amount from the sales table. They also both use the same WHERE clause to filter the sales data to only include sales from the last quarter. The WHERE clause uses the DATEADD function to subtract 1 quarter from the current date (GETDATE()) and only includes sales where the sale_date is greater than or equal to this date and less than the current date.\\n\\nThe main difference between the two queries is that the expert answer uses a subquery to first select the sale_amount from the sales table with the appropriate date filter, and then sums these amounts in the outer query. The submission, on the other hand, does not use a subquery and instead sums the sale_amount directly in the main query with the same date filter.\\n\\nHowever, this difference does not affect the result of the query.
