F doc page length

Summary

For #172 (closed). See also community channel. Since I was explaining the page_length parameter anyway, I wrote a short example for the documentation.

Focus

Only new docs. Is it understandable? Do all links point to the correct targets?

Test Environment

make doc
firefox build/doc/html/tutorials/paginated_queries.html

Check List for the Author

Please, prepare your MR for a review. Be sure to write a summary and a focus and create gitlab comments for the reviewer. They should guide the reviewer through the changes, explain your changes and also point out open questions. For further good practices have a look at our review guidelines

• Up-to-date JSON schema (or not necessary)
